The effects of PTFE on the electrode performance and on the structure of the catalyst layer in Raney nickel hydrogen electrode for alkaline fuel cell were investigated by using electrochemical and nitrogen adsorption methods. This study showed that the optimum PTFE content in the catalyst layer was 8 wt%, and that the Raney nickel hydrogen electrode was affected by the mass transfer resistance of hydrogen even in the beginning of polarization. The structural analysis of the catalyst layer using the electrochemical and nitrogen adsorption methods demonstrated that most entrances of the micropore were plugged with PTFE. The comparative study on Vulcan XC-72, one of the most used electrode material, showed that the extent of micropore plugging was a far greater in the Raney nickel than in Vulcan XC-72.
