A new fuel composition useful for catalytic fuel cells is made up of at
least two components. The primary fuel component is a surface active
compound, such as methanol, that is a source of and acts to prevent
unwanted decomposition of the auxiliary fuel. The auxiliary fuel is a
hydrogen-containing inorganic compound with a high reduction potential,
such as NaBH.sub.4, which acts as a highly reactive source of energy and
serves to catalyze the catalytic oxidation of the primary fuel.
