• C212 Degradation Characteristics of Polymer Electrolyte Membrane Fuel Cell Resulting from Cold Start

抄録

In polymer electrolyte fuel cells (PEFCs), the produced ice below freezing temperature has the potential to adversely affect the structure of cathode catalyst layer (CL) and the cell performance. This study investigated degradation characteristics of a PEFC resulting from produced ice in CL. To repeat cold start in a short time, we introduce N_2 purge to remove the produced ice below freezing temperature. The cycle of cold start at -10℃ makes the cell performance gradually-degraded in high current density region. The freezing period becomes longer and the cell resistance at shutdown increases after the cold start cycle. The results suggested that produced ice degrades the contact of CL and micro porous layer.
