  • Fuel cell with pulsed anode potential
    Publication number: 20030022033
    Abstract: A fuel cell having an electrode-electrolyte unit, with an anode catalyst via which the catalytic activity in the fuel cell is reduced by carbon monoxide. An arrangement for varying the anode potential in a pulsed manner such that carbon monoxide adsorbed at the catalyst is also provided. In this way, power losses caused by carbon monoxide adsorptions at the anode catalyst are reduced.
