AbstractIn this paper a hydrogen fuel cell is operated in the absence of a membrane at 60°C. The fuel cell was fed a nonhumidified hydrogen fuel and a 2 M Fe(ClO4)3, 0.22M Fe(ClO4)2, and 0.2 M HClO4 oxidant catholyte. A 3-D carbon cathode in conjunction with a 0.5 M HClO4 liquid electrolyte was used to eliminate the membrane. Nonoptimized maximum power density upwards of 220 mW/cm2 was achieved with a total Pt content of the fuel cell as low as 0.05 mg/cm2. Elimination of the PEM and reduction in total fuel cell Pt-catalyst content are expected to offer significant cost savings over conventional fuel cell technology. © The Electrochemical Society.
