Abstract:

Investigations were conducted toward developing high drain fuel cell electrodes for acid media. Activated carbon electrodes were prepared, wetproofed with paraffin or Teflon, and catalyzed with platinum. The wetproofing agent was applied by immersion or electrodeposition and the catalyst applied by chemical decomposition of H2PCl6 solutions. Half cell studies with hydrogen anodes and oxygen air cathodes showed that electrochemical performance is essentially the same for paraffin and Teflontreated electrodes however, the life of the Teflon-treated electrodes under equal conditions of load is greater than that for paraffin-treated electrodes. An equation that describes the cathodes polarization behavior for heterogeneous porous electrodes expresses a simple relationship between current density and polarization and is valid in the range of practical current densities.
