Abstract

An anode (3) for a direct liquid fuel cell in which hydrogen gas is generated as a result of a fuel oxidation or decomposition reaction. The surface of the anode (3) which is intended to face the electrolyte chamber (5) of the fuel cell is substantially completely covered with a polymeric material (6) which prevents at least about 80 % of the generated hydrogen gas to pass through the anode into the electrolyte chamber (5).
