A sealer for use in an all-solid-state secondary battery provided with a sulfur-containing solid electrolyte, characterized in that the sealer contains a resin and a particulate fatty acid metal salt dispersed in the resin, and the particulate fatty acid metal salt is a particulate fatty acid metal salt in which a fatty acid is coordinated on the surfaces of the metal particles having a mean particle diameter of not more than 1000 nm. The all-solid-state secondary battery is capable of suppressing the generation of the hydrogen sulfide.

In, for example, a direct methanol type fuelcell, fuel is allowed to be injected little by little when the fuel is injected and supplied from the outside to a fuel receiving part reduced in the amount of remaining fuel on the fuelcell body side and an electromotive part can be prevented from being damaged by keeping the pressure in the fuel receiving part at a fixed level or less when the fuel is injected. Specifically, when a fuel CL filled in a refuelling container C is injected into a fuel receiving part T in several lots, a fuel injecting operation is repeated in which the volume of the refuelling container C is shrunk and reduced to supply the fuel into the fuel receiving part T in a proper amount and then the original volume of the refuelling container is restored to thereby absorb the atmospheric gas in the fuel receiving part T, which makes it possible to inject fuel continuously without any hindrance to the injection of the fuel.

A stainless steel material for a fuel cell, used for a fuel cell or a cartridge for the fuel cell, having a magnetic permeability of 1.000 to 2.500, and forming a layer having a value of chromium atomic %/iron atomic % of not less than 3.0 in the most surface thereof, and/or the layer of thickness of not less than 12 nm calculated as SiOhaving an oxygen atomic % of not less than 20%. Even when brought into contact with the content solution exhibiting acidity of the fuel cell, the stainless steel material reliably suppresses the elution of metal ions thereof.
