Abstract
A process for producing electrical energy with the aid of a fuel cell, which includes the steps of reforming an organic fuel, removing carbon monoxide from the reformate, and reacting the hydrogen present in the reformate with oxygen, in a fuel cell, to thereby produce electrical energy. The carbon monoxide is removed from the reformate by treating the reformate in a bioreactor which contains a thermophilic microorganism strain which metabolizes carbon monoxide, under anaerobic conditions, to give carbon dioxide and hydrogen.
