The output density and volume of the fuel cell employed for Honda Motor Co Ltd's "Clarity Fuel Cell" fuel cell vehicle (FCV) were increased by 50% and reduced by 20%, respectively, by improving reaction efficiency (See related article).

In the past, water generated by a chemical reaction sometimes clogged up hydrogen and air passages. This time, generated water is circulated in the cell to prevent the passages from being clogged up, improving reaction efficiency.

The fuel cell employed for Honda's "Clarity Fuel Cell" FCV

The cell consists of (1) a "hydrogen electrode," which transmits hydrogen, (2) "air electrode," in which oxygen in the air reacts with hydrogen, and (3) "electrolyte" between the two electrodes. Hydrogen at the hydrogen electrode passes through the electrolyte and chemically reacts with oxygen at the air electrode, generating electricity.

The cell consists of an "electrolyte" (center) sandwiched between a "hydrogen electrode" and "air electrode." Hydrogen ions from the hydrogen electrode pass through the electrolyte and go to the air electrode. Then, it reacts with oxygen, generating electricity and water.
