Sodium borohydride (NaBH4) in the presence of sodium hydroxide as a stabilizer was a hydrogen generation source with high hydrogen storage efficiency and stability.The catalyst has a key role in H2 generation reaction from NaBH4.We reported that a structured Fe-B catalyst prepared by capacitive adsorption of Fe ions followed by alkaline chemical reduction step.A porous carbon clothes could hold Fe ions with capacitive current and it was reduced by NaBH-4 hydrolysis.The loading amount and the density of Fe-B electrodes were strongly dependent of the experiment conditions of an applied potential at the first step and the reduction time at the second step.We observed that Fe-B showed a stable hydrogen production from NaBH4 without fast degradation phenomena; even if the production rate was slower than that using Co-B or Ni-B.
