TL;DR: In this paper, a novel analytic method of MEA parameters is proposed with high accuracy and stability, which does not require high sampling frequency and data filtering of voltage signals anymore. But the method is not suitable for large-scale fuel cell stacks, and it cannot be applied to evaluate the MEA consistency of a long-time-stored seven-cell stack and recognizes part of the membranes ineffective.

Corrosion of metallic bipolar plates accelerated by operating conditions in a simulated PEM fuel cell cathode environment
TL;DR: In this paper , accelerated stress tests were conducted to reveal the operation-induced corrosion mechanisms of typical SS316L bipolar plates (BPs) in fuel cell stacks to achieve an extremely high power density, and thus suitable for vehicle applications.
