| description | The present invention concerns a method (and the associated device) for supplying a fuel cell (3) with a hydrogenated gas (G), consisting essentially of hydrogen, at a pressure lower than or equal to 5.105 Pa and at a temperature lower than 250°C, and generally lower than 200°C. Said method comprises: a) burning at least one hydrogenated-gas generating solid pyrotechnic charge (7) in order to produce a hot, pressurised hydrogenated gas (GO) containing at least 70 mol% hydrogen; b) supplying and operating an open-cycle two-reservoir heat engine (2) with at least one portion of said hot, pressurised hydrogenated gas (GO) containing at least 70 mol% hydrogen, that has been produced; said heat engine (2) then delivering an expanded and cooled hydrogenated gas (Gl) corresponding to said at least one portion of this hydrogenated gas (GO) that has been produced; c) supplying said fuel cell (3) with a hydrogenated gas (G) corresponding to at least one portion of said hydrogenated gas (Gl) delivered by said heat engine (2), expanded to a pressure lower than or equal to 5.105 Pa and cooled to a temperature lower than 250°C, and generally lower than 200°C. Said method has a particularly advantageous energy balance. |
