FUEL CELL MODEL

Participants: Keith Promislow, Chaoyang Wang, Pengtao Sun, Jinchao Xu

We propose a model of liquid and heat flux, ignoring the gas dynamics. More specifically we assume that the pressure and vapour pressure are constant and solve for the water volume fraction and the temperature as functions of space and time. The water motion is driven by capillary pressure, and a heat flux is generated by boundary conditions. The two equations are coupled by condensation, which exchanges heat for liquid, generating a liquid flux opposite that of the heat flux.

Numerical simulation is done with the adaptive finite element method
