Abstract
A porous, nanostructured semiconductor material for hydrogen storage in fuel cell applications was discussed. It was found that the material is competitive with metal hydride storage materials, but contains only carbon and silicon, reducing both its cost and environmental impact. It was observed that the core skeleton structure of this material is unaltered when cycling from full hydrogen storage to full hydrogen depletion, removing engineering complications associated with expansion/contraction of the material. Hydrogen stored in the nanomaterials and combined with oxygen in a fuel cell was found to have an energy density higher than Li batteries.
