.... The developed model is based on the governing equations of heat, mass, and momentum transport, which are solved together with global reforming reaction kinetics. The result shows that the heat generation within the cell depends mainly on the initial fuel composition and the inlet temperature. This means...

..., the project behind this work is aimed at detailed methanol kinetics measurements, so different variants of reaction kinetics for methanol are under consideration. Ohmic losses in the porous matrix and the electrolyte are to be considered, together with a double layer capacity. If desorbing formiate ions...

... a sensitivity analysis with respect to the physical reference case and geometric parameters. The results indicate that surface diffusion might play a major role for the reaction kinetics, but only if the air pore is void of liquid water. In contrast, the formation of liquid water in the gas pores will turn...
