Test Procedures for the Evaluation of the Performance and Stability of Direct Ammonia Fuel Cells

Energy Technology, Volume 14, Issue 7, July 2026.
A comprehensive electrochemical test protocol for direct ammonia fuel cells (DAFCs) is introduced, combining static, dynamic, and open‐circuit load regimes with three‐electrode operation to deconvolute anode and cathode contributions. Voltage decay is shown to be dominated by reversible anode deactivation driven by fuel depletion, with full performance
