Process for generating electrical power using a fuel cell

The electrical recovery of energy, comprising using a fuel cell by reforming an organic fuel, removing carbon monoxide from the reformate and converting the hydrogen in the reformate and the oxygen into electrical energy, where the reformate is treated in a bioreactor containing a thermophilic microorganism strain to remove carbon monoxide, is new. An Independent claim is also included for a polymer electrolyte fuel cell containing a polymer electrolyte membrane having one side coated with an anode catalyst and the other side coated with a cathode catalyst. Both catalysts are covered with a gas distributor structure for electrically contacting and introducing and removing the reaction media. The microorganisms are immobilized on the gas distributor structure for the anode.
