Brændselscelle med pulsformet variabelt anodepotential

摘要

The invention concerns a fuel cell (1) comprising an electrode-electrolyte unit (2, 3, 4) with an anode catalyst whose catalytic activity in a fuel cell is reduced by carbon monoxide and with means (5, 6) for varying the anode potential in pulsed manner such that carbon monoxide which has been adsorbed on the catalyst is oxidized. In this way, power losses owing to carbon monoxide adsorption at the anode catalyst are reduced.
