摘要：
Water management is important for proton exchange membrane fuel cell (PEMFC). To maintain highly efficient and stable operation of PEMFC, water generated in PEMFC needs to be migrated in time. An inner dehumidification technique is proposed to remove the water inside the PEMFC stack. Two inner condensing units are set near the cathode outlet to cooling the moisture gas. Water vapor in the flow channel will transfer directly to the outlet to supplement the vapor loss due to condensing. As a consequence, water flooding is sufficiently mitigated inside PEMFC. The experimental results show that th...
