Performance of the DHHPFC under various electrolyte conditions with NPGL30 as the catalyst at 60°C.

(A) Dependence of the N₂H₄ concentration, the H₂O₂ concentration was fixed at 20 wt.%; (B): Dependence of the H₂O₂ concentration, N₂H₄ concentration was fixed at 10 wt.%. The flow rates of the fuel and oxidizer were 1.4 and 4.2 mL min⁻¹, respectively. (C) Dependence of the N₂H₄ flow rate as the cathode flow rate was fixed at 4.2 mL min⁻¹; (D) Dependence of the H₂O₂ flow rate as the anode flow rate was fixed at 1.4 mL min⁻¹. The concentrations of N₂H₄ and H₂O₂ were 10 wt.%.
