TL;DR: In this article, the degradation mechanisms of proton exchange membrane (PEM) fuel cells are elaborated systematically according to parameter characteristics, microstructure, and aging reactions, and further investigation into improved fuel cell durability via mechanism analysis, condition optimization, control strategy development, structural design of the membrane electrode assembly, and component material development.

TL;DR: In this article, the effect variables of pressure drop are reviewed firstly, then estimations of the theoretical pressure drop were reviewed mainly based on the following four aspects: Bernoulli's equation, two-phase flow multiplier, Darcy's law and artificial intelligence.

TL;DR: In this article, the specific approaches, including regulating fuel cell temperature, inlet pressure, and inlet relative humidity (RH), were adopted to fulfill this strategy in case the real cathodic pressure drop (PD) surpasses the theoretical control line.

TL;DR: In this article, an impedance-based measuring method of the zero-phase ohmic resistance is presented, which adjusts the measuring frequency to confine the impedance point within the ±3° sampling limitation area so as to guarantee the accuracy of 0.01mΩ.

TL;DR: In this article, the authors improved the linear sweep voltammetry (LSV) by taking short circuit of PEMs into consideration and a mass spectrometry assisted with hydrogen pump is proposed with no need of calibration with standard gas.
