Abstract
A novel filtration method for preparation of gas diffusion electrodes for fuel cells is proposed. This method, which is a modification of the conventional dry method, has the merits of both wet and dry techniques. The electrode performance is improved due to better structure, controlled hydrophobicity and less compaction. To compare the effectiveness of the method, Raney-Ni/PTFE anodes for use in a KOH fuel cell were made. Their electrochemical performance was compared with similar electrodes produced by the dry method by other research groups, under the same conditions. The filtration method electrodes performed better between temperatures of 25°C and 75°C. The electrode exhibited no significant degradation of activity in the first 180 h at 100 mA cm-2 anodic load.
