Using Natural-Occurring Products To Build Hydrogen Fuel Cells

In research aimed at reducing American dependence on petroleum-based fuels, a group of Agricultural Research Service (ARS) scientists has found a way to replace the petroleum used in today's hydrogen fuel cell membranes with naturally occurring products.

Justin Barone and colleagues in ARS' Environmental Management and Byproduct Utilization Laboratory in Beltsville, Md., have conducted preliminary studies which suggest the possibility of replacing the conventional petroleum-based main membrane in hydrogen fuel cells with biological products.Hydrogen fuel cells have received a lot of attention as a possible energy conversion mechanism.

The coming of what's being called a renewable "hydrogen economy" is being touted as a feasible alternative to current economic reliance on nonrenewable fossil fuels.

In the hydrogen economy, hydrogen fuel cells would replace internal combustion engines in vehicles, and hydrogen would replace gasoline.

However, current hydrogen fuel cell technology is heavily dependent on petroleum to make both the fuel cells and the hydrogen fuel.In biology, membranes surrounding cells routinely conduct hydrogen ions through the cell walls.

Borrowing from this idea, Barone and his colleagues have focused their research on bio-based, nonpetroleum membranes made from naturally occurring products to conduct the hydrogen ions moving in and out of fuel cells.

Further development of this type of innovative energy-generation technology would help America move away from the widespread use of petroleum and would address the need to explore alternative energy sources.

TITLE: BUILDING HYDROGEN FUEL CELLS USING NATURAL OCCURING PRODUCTS

ALAM BA NINYO NA NATUKLASAN NG MGA AGRI-EXPERT ANG PAMALIT SA PETROLYO NA GINAGAMIT SA HYDROGEN FUEL CELL MEMBRANE.

BATAY SA GINAWANG PRELIMINARY STUDY NG GRUPO NI JUSTIN BARONE NG ARS ENVIRONMENTAL MANAGEMENT AND BYPRODUCT UTILIZATION LABORATORY, NATUKLASAN NILA ANG POSIBILIDAD NA PALITAN ANG CONVENTIONAL PETROLEUM-BASED MAIN MEMBRANE NG HYDROGEN FUEL CELL NG BIOLOGICAL PRODUCTS.

ANG HYDROGEN FUEL CELLS AY TINUTUTUKAN NA MABUTI NGAYON BILANG POSIBLENG ENERGY CONVERSION MECHANISM BILANG ALTERNATIBO SA NAKASANAYAN NANG PAGGAMIT NG FOSSIL FUELS.

SA HYDROGEN ECONOMY, PAPALITAN NA NG HYDROGEN FUEL CELLS ANG INTERNAL COMBUSTION ENGINE NG MGA SASAKYAN KUNG SAAN ANG GASOLINA AY PAPALITAN NA NG HYDROGEN.
