Performance of Polymer Electrolyte Fuel Cell Formed from Pt-loaded Activated Carbon with Various Pore Structures

抄録

Carbon supports of electrocatalysts have recently attracted much attention for improving the performance of polymer electrolyte fuel cells (PEFCs). In this study, the PEFCs were formed using activated carbon loaded with platinum of various pore structures in the cathode catalyst layer. The performance of the PEFC at the relative humidity of 100% was dependent on the specific surface area and the mean pore diameter. The behavior was correlated with the results obtained using rotating disk electrodes in a previous study. The PEFC performance was also examined in a low-humidity condition and found to be also dependent on the pore structure.
