Abstract
Tomographic neutron imaging was used to visualize water distribution inside polymer electrolyte membrane fuel cell (PEMFC) investigating influence of hydrophobicity gradients within cathode micro porous layer (MPL) and catalyst layer. Water content inside a volume of interest was studied, comparing water content inside layers in a region under flow field land and in the adjoining region under flow field channels. Polarization curves were attained, investigating influence of water distribution and content on the performance of these three cells. Hydrophobizing the cathode MPL increased the water content inside the cell, which resulted to a performance decrease obtained from the respective polarization curve.
