Sodium tetrahydroborate (NaBH₄) was used as a fuel source for hydrogen-oxygen fuel cell. The oxalic acid, Ag⁺, Cu²⁺ and Ni²⁺ accelerates the hydrogen (H₂ gas) evolution from the self-hydrolysis of NaBH₄ at 30 °C. Kinetics of H₂ gas generation was evaluated as a function of catalyst, NaBH₄, sodium hydroxide concentrations at different temperatures. Hydrolysis NaBH₄ follows first-, and fractional-order kinetics with [BH₄^-], and [H⁺] respectively. The hydrolysis of NaBH₄ decreases with increasing [NaOH] at 30 °C. The metal ions (Ag⁺, Cu²⁺, and Ni²⁺) catalyzed the evolution of H₂ gas and hydrolysis followed zero-order kinetics with respect to the metal ions. Hydrolysis of NaBH₄ was catalyzed by metal ions and hydrogen ions simultaneously. The activation parameters were calculated and found to be activation energy = 54.9, 59.7, 62.7 kJ/mol, enthalpy of activation = 52.4, 57.5, 60.2 kJ/mol and entropy of activation = −62.2, −48.2, −49.6 J/K/mol for Ag⁺, Cu²⁺ and Ni²⁺, respectively. The catalytic activity of depends on the reduction potential of metal ions; Ag⁺ (0.799 V) ˃ Cu²⁺ (0.341 V) ˃ Ni²⁺ (−0.257).
