In order to keep the cell under small temperature change and exhaust the heat of reactions properly during the operation, the usage of an integrated water-cooled channel bipolar plate can replace the conventional water-cooled runner plate. The model can improve the problem of the thickness in PEMFC stack; and assemble the metal foam in the water-cooled flow channel to enhance the water-cooled flow channel cooling and temperature control capabilities. With the view to absorbing the best performance of PEMFC, the model was measured by different water temperature and other parameters in the study; meanwhile it was estimated temperature distribution in each part of PEMFC by thermocouple to verify that the model can control the cell temperature accurately and dissipate the heat effectively. It can be seen from the experimental results that the design of the water-cooled flow channel filled with the metal foam is applied to the bipolar plate of the water-cooled flow channel, which can take away the excess waste heat during the PEMFC reaction and control the PEMFC temperature by using the water temperature, So that the average distribution of PEMFC temperature, but also to reduce the battery thickness.
