Water management is one of the crucial factors regarding the performance and durability of low temperature PEM fuel cells. Amongst other factors, the water balance in an operating fuel cell can be influenced by the humidification of the reaction gase

The three-dimensional water distribution and water transport paths in the gas diffusion layer (GDL) and the adjacent micro-porous layer (MPL) of a polymer electrolyte membrane fuel cell (PEMFC) were analyzed during cell operation. The technique of qu

One key issue in high temperature polymer electrolyte membrane fuel cell (HT-PEMFC) stack development is heat removal at the operating temperature of 140–180 °C. Conventionally, this process is done using coolants such as thermooil, steam or press
Most of the transport processes of a fuel cell take place in the gas diffusion media and flow fields. The task of the flow field is to uniformly distribute the reactant gases across the electrochemically active area and at the same time ensure an ade

Publisher Summary Direct Methanol Fuel Cells (DMFCs) represents the only class of fuel cells in which one of the reactants is provided in liquid phase unlike the other, gas-fed, cell types. Owing to the comparatively easy handling of methanol, DMFCs

Quasi–in situ neutron tomography is applied to polymer electrolyte membrane fuel cell stacks for a cell-by-cell detection of liquid water agglomerates. Water distributions in the corresponding anodic and cathodic flow fields are analyzed separately
