... rendered adhesive by hydroxylation in a two-step water-borne process. (ii) A previously developed theoretical model is used to calculate the relative resistance and proton transfer rate. According to the model, a simple second order differential equation describes the entire process and established...

... the channel. The solution domain comprises seven regions, (two inlet channels, two diffusers, two active catalyst layers, and a membrane) and considers transport of hydrogen and water vapor in the anode and oxygen and nitrogen and water vapor in the cathode. The resulting set of coupled differential equations...
