Research of gas channels in proton exchange membrane fuel cells
The gas channels in proton exchange membrane fuel cell(PEMFC)distributes the reaction gas as evenly as possible to the whole fuel cell,which is crucial to the performance of the PEMFC.The structural design of the gas channels is one of the most active research fields.According to the structure type of gas channels,it can be divided into conventional gas channels,improved gas chan-nels based on conventional ones,bionic gas channels and three-dimensional complex gas channels.This study systematically analyzed the structure and research status of various gas channels,which can provide reference and guidance for the future design of PEMFC.
