- •
In-situ method to evaluate the ECSA of electrodes in an open-cathode PEMFC stack.
- •
Open-cathode evaluation made possible in nitrogen-purged gas-tight enclosure.
- •
Unlike cyclic voltammetry, all cells in a fuel cell stack measured simultaneously.
- •
High precision achieved using high data acquisition rates and low pass filtering.
- •
Electrode capacitance and hydrogen crossover rate obtained in the experiment.
