As the hydrogen gas is efficiently absorbed, the gas pressure inside the battery can be lowered, and the expansion of the battery case and electrolyte leakage can be prevented. It is possible to reduce the probability of corrosion of the resistance element due to the alkaline electrolyte and to adjust the proper resistance value according to the characteristics of the battery, as well as to increase the effective power and volumetric efficiency of the battery.
