Summary Zinc (Zn)–air fuel cells (ZAFCs) are one of the potential alternatives to fossil fuels. Because a flowing electrolyte can directly affect cell performance, we focused on the electrolyte management of a ZAFC. The ZAFC galvanostatic discharge was examined to determine its performance. The electrolyte concentration, temperature, and circulation rate were used as the operating parameters for discharge tests, and the relationship between electrolyte and cell performance was discussed based on the experimental results. To elucidate the effect of electrolyte‐flow, the computation fluid dynamic simulations have been first performed. The results revealed that the cell performance associating the remnant oxygen in the electrolyte channel
