.cndot. A hydrogen generation method comprises the steps of storing anhydrous ammonia fuel in liquid phase under pressure, vapourising the liquid ammonia into gaseous ammonia, generating electromagnetic radiation, and dissociating gaseous ammonia (NH3) into a mixture of gaseous nitrogen (N2) and gaseous hydrogen (H2) by means of the electromagnetic radiation according to formula: 2 NH3 .fwdarw. N2 + 3 H2 .cndot. A hydrogen generator comprises an ammonia tank, an ammonia vapouriser, an electromagnetic wave source, and an electromagnetic dissociator. Preferably, the electromagnetic wave source generates electromagnetic radiation in the vacuum ultraviolet (VUV) region of the spectrum, at wavelengths shorter than 254 nm. The electromagnetic wave source may be a dielectric barrier discharge (DBD) lamp or an excimer lamp. This invention relates to hydrogen generators, and the principal use of the invention is for fuel-cell vehicles.
