• D201 Effect of Air Flow Conditions on Water Transport in Air-Breathing PEMFC with Dead-End Hydrogen Flow

抄録

As a smaller and lighter hydrogen PEFC, we adopted "Dead-end mode" and "Air-breathing" systems and tried to improve the cell performance with a small fan. In this paper, the effects of cathode air flow rate and cell temperature on the cell performance were investigated experimentally. It was shown that under low relative humidity conditions higher flow rate makes the CCM drier and causes dryout, but suppresses the increase in the cell temperature by the reaction heat. The increase in the cell temperature also induces dryout, so appropriate temperature management as well as water management by the small fan is important for stable high cell performance of this PEFC system.
