Abstract
The present invention features a new iron material for use in situ with a hydrogen-air fuel cell, to generate the hydrogen to fuel the fuel cell. The iron material is made up of freshly-ground particles of iron, ranging in diameter size from approximately 25 to 1,200 .mu.m, with an average-sized distribution having at least twenty per cent (20%) of the particles less than about 300 .mu.m in diameter, and having an average particle density approximately ranging from about 1 to 7.8 g/cc, and a surface area greater than approximately 0.001 meters.sup.2 /g. The particles are in a freshly ground state, in situ, for enhancing their reactivity in producing hydrogen for the fuel cell.
