TL;DR: In this article, the main difference between fuel cells used in vehicles and those used as fixed power is the load cycling, which sometimes leads to water management and gas transport problems, which further leads to degradation of fuel cell performance and attenuation of internal parts.

TL;DR: In this paper, a formula to predict the PEM fuel cell lifetime is presented based on the vehicular operation records and the tested results in the lab, where the difference between the vehicle operation condition and the test is taken into consideration.

TL;DR: In this article, an electrochemical phase-field model is established to simulate dendrite growth of electrodeposited zinc, and several measures including the pulsating current and the electrolyte flow are taken to suppress dendritic growth in the charging process.

TL;DR: In this paper, the most suitable electrochemical diagnostic method for on-line diagnosis of on-board proton exchange membrane fuel cell stacks is studied, and the results show that optimized electrochemical impedance spectroscopy based on dynamic multi-frequency analysis might be the more suitable diagnostic method.

TL;DR: In this paper, phase-field simulation is used to reveal two phenomena of bubble detachment and bubble coalescence located in the charging electrode on both sides, and two types of rechargeable zinc-air battery are developed on the basis of different tri-electrode configurations, demonstrating that the charging performance of the battery with electrolyte flow (Ⅰ) is better than that of battery with the partially insulated electrode(Ⅱ), while the battery is superior to the battery Ⅰ in discharging performance, cost and portability.
