Hydrogen fuel cell with two-cycle catalyst electrodes

摘要

In order to disinhibit the Volmer reaction mechanism of hydrogen fuel cells, catalyst electrode discs (4) fastened on a horizontally mounted shaft (3) according to an electrical wiring diagram, are rotated across two-phase regions (gas phase)/(electrolytic solution). As a result, the reaction-inhibiting shielding of electrochemically active centres on the catalyst electrode surfaces by gas-impermeable electrolyte solution layers and films, with respect to the gas phases to be adsorbed, is largely eliminated. The use of membrane structures is likewise obviated. The efficiency of hydrogen fuel cells can be considerably improved by conducting the reaction in this manner.
