Global Legislators Organization for a Balanced Environment USA (GLOBE USA) and the Environmental and Energy Study Institute (EESI) sponsored a Congressional briefing to discuss hydrogen and fuel cell technology. Representative Nancy Johnson (R-CT), Representative Mark Udall (D-CO) and Senator Jim Jeffords (R-VT), members of GLOBE USA, hosted the briefing. Representative Udall provided opening remarks to offer their legislative perspectives. In the United States today we are faced with many energy challenges, ranging from regional power supply crises and sharply escalating energy prices to oil extraction. According to the Wall Street Journal, Americans are more concerned about energy now than they have been for decades. The time is ripe for renewable and sustainable energy technologies to play a much larger role in our future, and one of the key elements of this new energy economy is hydrogen and fuel cells. There are numerous bills that have been introduced in Congress that deal with renewable and emerging energy technologies, including hydrogen and fuel cells. Hydrogen is a renewable energy resource, and it is the most abundant element in the universe.

http://www.iclei.org/efacts/fuelcell.htm

Extractions: Fuel cells have a similar structure to a battery, with two porous electrodes separated by an electrolyte. Electricity is produced by a chemical reaction between a hydrogen-based fuel and an oxidant (usually oxygen) inside the fuel cell. Figure 1 is a diagram of the electrochemical reaction which takes place inside a fuel cell. Hydrogen (H ) flows over the anode (the negative electrode) and splits into positively charged hydrogen ions, and electrons which carry a negative charge. The electrons flow through the anode to the external circuit, performing useful work (this is the electric current generated) while the hydrogen ions pass through the anode and into the electrolyte, moving towards the cathode (the positive electrode). The electrons eventually return to the cathode which is supplied with oxygen (O ). At this point the electrons, hydrogen ions and oxygen react to form water (H O) and heat. In stationary fuel cell power plants this heat can be captured and used for process heat in industries or space heating ( co-generation ). As long as the fuel cell is supplied with hydrogen and oxygen, this electrical production can continue indefinitely.

The current focus is on hydrogen's use in fuel cells. power vehicles or to provide electricity and heat to buildings. The primary fuel cell technologies under development are: Phosphoric Acid Fuel Cells A phosphoric acid fuel cell (PAFC) consists of an anode and a cathode made of a finely dispersed platinum catalyst on carbon paper, and a silicon carbide matrix that holds the phosphoric acid electrolyte. This is the most commercially developed type of fuel cell and is being used in hotels, hospitals, and office buildings. The phosphoric acid fuel cell can also be used in large vehicles, such as buses. Proton-Exchange Membrane Fuel Cells The proton-exchange membrane (PEM) fuel cell uses a fluorocarbon ion exchange with a polymeric membrane as the electrolyte. The PEM cell appears to be more adaptable to automobile use than the PAFC type of cell. These cells operate at relatively low temperatures and can vary their output to meet shifting power demands. These cells are the best candidates for light-duty vehicles, for buildings, and much smaller applications. Solid Oxide Fuel Cells Solid oxide fuel cells (SOFC) currently under development use a thin layer of zirconium oxide as a solid ceramic electrolyte, and include a lanthanum manganate cathode and a nickel-zirconia anode. This is a promising option for high-powered applications, such as industrial uses or central electricity generating stations.
Device Ups Hydrogen Energy From Sunlight: Science News Online, Sept. 16, 2000
A recipe for a cleaner, healthier planet Take some water, add solar energy, extract hydrogen, and use it to power fuel cells for running cars and other machines. Then, collect their water emissions and start the procedure again.

Extractions: 70 Years Ago in Science News Week of Sept. 16, 2000; Vol. 158, No. 12 Peter Weiss Here's a recipe for a cleaner, healthier planet: Take some water, add solar energy, extract hydrogen, and use it to power fuel cells for running cars and other machines. Then, collect their water emissions and start the procedure again. One look at the list of ingredients in today's fuel cells, however, shows that this ideal isn't yet being followed. Because processes that use sunlight to extract hydrogen remain costly and inefficient, fossil fuels still supply the hydrogen in most fuel cells. Hoping to break the fossil fuel habit, a team of Israeli, German, and Japanese scientists has created a device that boosts the efficiency of solar-powered hydrogen extraction by 50 percent. The group placed a photovoltaic cell on top of two flat, finger-long electrodes. The combination "is very efficient in converting solar energy [into an electric current] but also provides nearly the ideal voltage for splitting water" into hydrogen and oxygen, says team leader Stuart Licht of the Technion in Haifa, Israel. A water molecule splits, or undergoes electrolysis, at only 1.23 volts. Licht and his colleagues describe their device in the Sept. 14

Extractions: Oil Reserves Electricity Regulation Gas Regulation ... Distributed Power Fuel Cells Fuel cells could be a power company's dream: an efficient, combustion-less, virtually pollution-free power source, capable of being sited in downtown urban areas or in remote regions, that runs almost silently, and has few moving parts. But fuel cells are more reality than dream. Using an electrochemical process discovered more than 150 years ago, fuel cells began supplying electric power for spacecraft in the 1960s. Today they are being used in more down-to-earth applications: to provide on-site power for banks, police stations, and office buildings. In the near future, fuel cells could be propelling automobiles and allowing homeowners to generate electricity in their basements or backyards. Fuel cells operate much like a battery, turning oxygen and hydrogen into electricity in the presence of an electrically conductive material called an electrolyte. Unlike a battery, however, fuel cells never lose their charge. As long as there is a constant source of fuel usually natural gas for the hydrogen and air for the oxygen fuel cells will generate electricity. MORE ON...

Extractions: Phosphoric Acid Fuel Cells Phosphoric acid fuel cells were the first fuel cells to cross the commercial threshold in the electric power industry. More than 200 of these "first generation" power units are now operating in stationary power applications in the United States and overseas. Most are the 200-kilowatt PC25 fuel cell manufactured by the ONSI Corporation, including one that powers a police station in New York City's Central Park and another that provides supplemental power to the Conde Nast Building at 4 Times Square in New York. The largest phosphoric acid fuel cell to be tested is an 11-megawatt power plant sited in Japan. As the name implies, these fuel cells use liquid phosphoric acid as the electrolyte. The electrodes are made of carbon paper coated with a finely-dispersed platinum catalyst. The catalyst strips electrons off the hydrogen-rich fuel at the anode. Positively charged hydrogen ions then migrate through the electrolyte from the anode to the cathode. Electrons generated at the anode travel through an external circuit, providing direct current electric power, and return to the cathode. There the electrons, hydrogen ions and oxygen form water, which is discharged from the cell. Phosphoric acid fuel cells operate at around 150 to 200 degrees C (about 300 to 400 degrees F), above the boiling point of water. (This is one reason why phosphoric acid is preferred although it is a less efficient conductor of electricity than other acidic electrolytes Other acid electrolytes that require water for conductivity don't have this capability.)
