PURPOSE:To provide a hydrogen battery in which cobalt deposition to a separator is suppressed and short circuit between a positive electrode and a negative electrode is prevented even if a hydrogen storage electrode containing cobalt is used. CONSTITUTION:According to an experiment, in the case that an electrolytic solution containing a complex forming agent to form a complex using a cobalt ion as a core is used for a hydrogen battery provided with a hydrogen storage electrode which is prepared by mixing cobalt powder with hydrogen storage alloy powder, an improved charged capacity and an extended cycle life are achieved as compared with the case an electrolytic solution containing no complex forming agent. It is possibly because the cobalt ion dissolved in the electrolytic solution from the hydrogen absorbing electrode is taken in the complex forming agent and cobalt deposition to the separator is inhibited. |
