文摘

A battery based on ammonia and copper salts was used to produce electricity. Quaternary ammonium-based poly(phenylene oxide) membranes were tested. The synthesized membranes had different ion exchange capacities and thicknesses. The power density of the BTMA membrane (40% DF, 50 μm thick) was 106 ± 7 W m−2. Energy recovery was estimated to reach 7.0% relative to the Carnot efficiency.
