Heat flux voltage loss

At this level of the model, consider to be given the local current density i, the anode and cathode catalyst temperatures (da and 6c), the anode and cathode channel vapor concentrations (c and Cc), the anode channel hydrogen concentration (ch), and the cathode channel oxygen concentration (Co)-To be determined from the MEA model are the local cell voltage v, the diffusive water flux through the membrane / from cathode to anode, and the heat generated due to membrane resistance and cathode overpotential losses. As mentioned above, in this simplified model, the membrane resistivity is taken to be constant. Other resistances (except to in-plane currents in the bipolar plates in the stack model) are neglected.
