PCT No. PCT/SE94/01218 Sec. 371 Date Jun. 18, 1996 Sec. 102(e) Date Jun. 18, 1996 PCT Filed Dec. 19, 1994 PCT Pub. No. WO95/17773 PCT Pub. Date Jun. 29, 1995A method for producing electric energy in a biofuel-powered fuel cell, the metal in the first acid metallic salt solution forming a redox pair having a normal potential between -0.1 and 0.7 V and the metal in the second acid metallic salt solution forming a redox pair having a normal potential between 0.7 and 1.3 V, both metals preferably being vanadium which forms the redox pairs vanadium(IV)/(III) and vanadium (V)/(IV), respectively; carbohydrate being supplied as fuel to the first reactor (1) and the reaction in the first reactor (1) being effected in the presence of platinum or ruthenium as the first catalyst (2).
