Study on Water Transport Mechanisms of the PEMFC Based on a Visualization Platform and Water Balance Model

It is widely acknowledged that the water balance issue is extremely important for improving the performance and durability of the proton exchange membrane fuel cell. In the presented paper, the visualization platform of the single fuel cell and the water balance model were built to investigate the w...
