A stable solid state H 2S—O 2 fuel cell has been developed and operated at 1 atm and 20–90°C. A series of anode catalysts has been examined using Nafion ® as a common proton conducting membrane; those containing Pd and Pt were found to be effective using H 2 or H 2S as the anode feed gas, but MoS 2—C catalysts were effective for use of H 2S but not for H 2. The highest potential attained using H 2S and Pd/ C catalyst was 722 mV (theory: 1140 mV). When H 2S was used as anode feed the potential decreased up to 35% over 24 h as sulfur was deposited on the anode. The efficiency of the cell increased with temperature up to 90°C.
