Abstract :
Neutron imaging technique was performed to visualize the water distribution and movement at flow channels on operating proton exchange membrane fuel cell (PEMFC). According to operation conditions (inlet humidity ratio, temperature, and flow field geometry), the phenomena of water content and movement are investigated and their effects for the fuel cell efficiency are discussed
