Line Plot from Scientific Research

Simulated and experimental polarization curves for a pristine BPM (orange and blue) and for a BPM with added metal oxide catalyst (cat. BPM) for WF and WD currents at 25 °C (green, purple and red). For WF currents, we have to include Langmuir adsorption on the metal oxides (purple) for [H + ] and [OH − ], otherwise the WF currents increase too quickly (green). For the low currents shown, [H 2 O] is constant in the hydrated polymers.
