Abstract

Hydrogen offers the best energy carrier from environmental point of view. It is theoretically an efficient way to use hydrogen. There are some problems emerging which might be negligible which could be solved by scientific ways. Hydrogen is produced by fossil way and the reduction of CO2 emission is not added. The storage of hydrogen needs a low temperature and high pressure. The greatest problem is how to chouse the catalysts and electrode materials. Generally, they are noble metals and even working with clean hydrogen the CO concentration has to be kept as low as 10 ppm. Carbon monoxide on the nobel metal surfaces has stronger bond than adsorbed hydrogen atoms, so it may poison the active catalysts surface. In the present paper we are going to support to find the optimal working conditions of fuel cells.
