Optional FRA for EIS measurements (1mHz to 40kHz)

Figure 1: PEM fuel cell hydrogen crossover acquired by linear scanning voltammetry using the Scribner 885 fuel cell potentiostat (red) and a commercial potentiostat (black). The small drop in current close to 0.4 VRE is a characteristic of the fuel cell. Test conditions given in the figure.

Figure 2: PEM fuel cell cyclic voltammetry data using the Scribner 885 Fuel Cell Potentiostat (red) and a commercial potentiostat (black). Cyclic voltammetry is used for in situ electrochemical active surface area characterization of PEM fuel cell electrodes. Conditions given in the figure.
