Abstract A suitable channel structure can lead to efficient gas distribution and significantly improve the power density of
fuel cells. In this study, the influence of two channel design parameters is investigated, namely, the ratio of the
channel width to the bipolar plate ridge width (i.e., the channel ridge ratio) and the channel depth. The impact
of these parameters is evaluated with respect to the flow pattern, the gas composition distribution, the temperature field and the fuel cell output capability. The results show that a decrease in the channel ridge ratio and an
increase in the channel depth can effectively make… More >
