A modified tank in series model for cogeneration of hydroxylamine and electricity in the nitric oxide/hydrogen fuel cell

This work presents a modified TSR model of the nitric oxide/hydrogen fuel cell operating in potentiostatic mode with the co-current flow direction. The developed model accounts for the component and the energy balances in gas channels, liquid catholyte and catalyst layers together with charge balances at electrode/electrolyte interfaces. The simulation results indicate the influence of catalyst selectivity and mass transfer on the distribution of concentration, temperature and current density.

► We model two-dimensional profiles in NO/H2 fuel cell using the TSR model. ► TSR model includes the charge balances defined as interface boundary conditions. ► Case studies indicate the influence of catalyst selectivity on the distribution of fields. ► TSR model is applicable for galvanostatic and potentiostatic operations of fuel cell.
