摘要：

In this work we present some preliminary data, such as permeability (gas crossover) of oxygen and hydrogen as a function of current density and other operational variables, aimed at establishing baselines for unmitigated hydrogen crossover of 3M's electrolyzer MEAs based on 3M's NSTF low-PGM loading catalyst and several types of perfluoro sulfonic acid based PEM membranes, both of which are widely commercially available (such as Nafion (TM) membranes), and membranes made by 3M. Experimental challenges associated with ex situ and in situ gas crossover measurements will be also discussed.
