PURPOSE:To suppress are rise in methanol vapor concentration and avoid a drop in a battery output by using solidified methanol with hydrate added as fuel. CONSTITUTION:Vapor phase methanol is supplied from solidified methanol to a fuel electrode and oxidant gas is supplied to an oxidant electrode 9 to cause oxidant electrode reaction to have electric energy generated. If a battery working temperature rises due to generation of Joule heat or the like by internal resistance of a battery at this time, methanol vapor concentration drops due to discharge of water in hydrate and an amount of methanol vapor which transmits to the oxidant electrode is reduced so that a drop in a battery output can be suppressed. Sodium carbonate.10hydrate (Na2CO3.10H2O) is used as hydrated and it can be replaced with sodium selenite.5 hydrate, sodium dihydrogen phosphate.12hydrate, or aluminum potassium sulfate.12 hydrate. |
