Abstract
The article presents an attempt to design the 2 W power source (PS) based on air–hydrogen fuel cells (FCs) and water–aluminium micro-generator as a hydrogen supply (WAHMG). Experiments concern FC’s breathing in compact arrangement and combined performance of FC + WAHMG. It turned out to be necessary to build a fan into FC stack provided the rotation speed of fan depends on the FC current. The highest power density of FC at optimal speed of air blowing was 101 mW cm−2. Electrical energy produced by FC was about 1.2–1.8 Wh per gram of Al in micro-generator. This value depends on the total yield of hydrogen in WAHMG and hydrogen losses due to purges.
