Summary:PROBLEM TO BE SOLVED: To avoid alteration of an active material and inhibit self discharge when an electrolyte supply type battery is in a dormant state.SOLUTION: A first supply line 30 for supplying an electrolyte 54 and a second supply line 32 and a third supply line 34 for supplying a liquid (a solvent 56) which does not function as the electrolyte are connected with a housing 12 of an electrolyte supply type battery 10. When electrode reaction is caused in a positive electrode 20 and a negative electrode 16 to conduct charging/discharging (operation), the electrolyte 54 is supplied from the first supply line 30 and the solvent 56 is supplied from the second supply line 32 and the third supply line 34. In the housing 12, the electrolyte 54 and the solvent 56 circulate in a state where the electrolyte 54 is sandwiched by the solvent 56 supplied from the second supply line 32 and the solvent 56 supplied from the third supply line 34 to form three layers. 【課題】電解液供給型電池が休止状態にある際、活物質が変質することを回避するとともに自己放電を抑制する。【解決手段】電解液供給型電池10の筐体12には、電解液54を供給するための第1供給ライン30と、電解液としては機能しない液体(溶媒56)を供給するための第2供給ライン32及び第3供給ライン34が接続される。正極20及び負極16に電極反応を生起させて充放電(運転)を行うときには、第1供給ライン30から電解液54を供給するとともに、第2供給ライン32及び第3供給ライン34から溶媒56を供給する。筐体12内では、第2供給ライン32から供給された溶媒56と、第3供給ライン34から供給された溶媒56との間に電解液54が挟まれるように3層となった状態で、電解液54及び溶媒56が流通する。【選択図】図2
