Abstract
For successful operation of a fuel cell, its lifetime should be at least 40,000 h. Durability tests are usually limited by certain/standard conditions. On the other hand, operation of a proton exchange membrane fuel cell (PEMFC) under real, nonstandard conditions may lead to an irreversible reduction in the device efficiency and/or degradation of its components. This review deals with the PEMFC performance under a variety of nonstandard conditions, including low and high humidity, and low and high temperatures. Mechanisms of influence of operating conditions on the device performance are identified and analyzed. It is shown that operation of a PEMFC with standard components under nonstandard operating conditions leads to irreversible consequences and reduces the expected lifetime of the device.
期刊介绍：
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
