Fuel cell design

Fuel cell operating principle, based on catalysis, electrons and protons separated from reacting the fuel, and to force the electrons to flow through a circuit which shall be made so that the electrical current. Another catalytic process, in the back, combined with the collected electrons, protons and oxidizing waste products (eg, water, carbon dioxide) formation is provided.

Hydrogen-Oxygen (proton exchange membrane fuel cell, PDMYH) design case, a proton-conducting polymer membrane (electrolyte), separates the anode and cathode. Fully understood the mechanism of proton exchange in the 1970s, this cell, "solid polymer electrolyte fuel cell" was known as.

Anode side, hydrogen, protons and electrons dissociate yayınarak anode catalyst. Protons through the membrane towards the cathode, the electrons, because the membrane is electrically insulating, and electrical current flows through an external circuit to form. Electrons and protons react with oxygen molecules on the cathode catalyst of water (the only waste product in this example) creates.

This is in addition to pure hydrogen-type fuel cells, diesel, hydrocarbon fuels such as methanol and chemical hydrides are also available. This type of waste, fuel cells, carbon dioxide and water.
