Fuel cells with alkaline electrolyte may subject liquid fuels like methanol and glycol to ''cold combustion'' at comparatively high power densities. The acid reaction products produced from the fuel dissolved in the electrolyte, however, neutralize the electrolyte so as to impair its function. The cell according to the invention is furnished with a separate container (5) for an aqueous phase containing the fuel. This aqueous phase also contains a base for neutralization of the acid reaction products. The cold combustion is taking place in a ''cell-sandwich'' (1) comprising a hydrophobic air cathode, an electrolyte consisting of an alkali hydroxide in an aqueous solution which is contained in a microporous separator (3) and the fuel anode (4). One side of the fuel anode (4) is in direct contact with the separator (4). The other side of the fuel anode is in direct contact with the aqueous phase in the container (5). |
