Dehydrogenation of Ammonia Borane (NH3BH3, AB) catalyzed by transition metal heterogeneous catalysts was carried out in non-aqueous solution at temperatures below the standard polymer electrolyte membrane (PEM) fuel cell operating conditions. The introduction of a catalytic amount (similar to 2 mol%) of platinum to a solution of AB in 2-methoxyethyl ether (0.02-0.33 M) resulted in a rapid evolution of H-2 gas at room temperature. At 70 degrees C, the rate of platinum catalyzed hydrogen release from AB was the dehydrogenation rate which was 0.04 g s(-1) H-2 kW(-1).
