摘要

铝吗?空气电池有望成为电动汽车的短期动力源。然而，放电过程中阳极腐蚀引起的寄生析氢一直被认为是铝铝进一步商业化的障碍。空气电池。本文着重研究了寄生反应的影响，以期更好地理解和管理寄生反应。在建立数学模型的基础上，研究了寄生析氢对电池流场、离子传质和电流密度的影响。此外，还对利用寄生演化氢提高总功率输出的可能性进行了评价。

Modeling of Parasitic Hydrogen Evolution Effects in an Aluminum−Air Cell†

The aluminum?air battery has potential to serve as a near-term power source for electric vehicles. Parasitic hydrogen evolution caused by anode corrosion during the discharge process, however, has long been recognized as an obstacle to further commercialization of the aluminum?air battery. This paper focuses on the parasitic reaction impacts, with an aim of better understanding and managing the parasitic reaction. On the basis of a mathematical model, effects of the parasitic hydrogen evolution on cell flow field, ionic mass transfer, and current density are investigated. Besides, the possibility of using the parasitically evolved hydrogen to increase the total power output is evaluated.

期刊介绍： Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
