Using a magnesium-based hydrolysis reaction that spontaneously produces hydrogen with a high kinetic and a high efficiency, this paper proposes a solution to supply a PEM fuel cell that permits production on demand. This solution is an instrumented reactor that uses capsules with magnesium powder and that controls the hydrolysis reaction in order to maintain a constant pressure. The hydrogen produced by the reactor is used to feed a PEM fuel cell in which variable electric loads are applied. By solving both the hydrogen supply and storage problems, such a system is particularly suitable for light mobility applications.
