抄録

As a smaller and lighter hydrogen PEFC, we adopted "Dead-end mode" and "Open-cathode" systems. Previous study showed that dry-out and anode flooding deteriorate the cell performance under drier air and higher current density conditions. In this paper, the effective methods to prevent dry-out and anode flooding were investigated experimentally using a single cell simulating the temperature distribution in a PEFC stack. It was shown that, in the condition that dry-out is caused easily by large increase in the cell temperature, the higher flow rate of the cathode air with low humidity improves cooling capacity, but also makes the MEA drier, resulting in dry-out. This means that it is difficult to suppress the dry-out by the control of the cathode air and other cooling method is needed. The results of experiment introducing a cooling channel showed that the control of the cooling air through the cooling channel is effective for suppressing the dry-out, and the control of the cathode air is also effective for suppressing the anode flooding.
