Fuel cell with an internal chamber, in which a gas storage device is placed

摘要

The fuel cell (1) has an inner space (11) defined by a tubular body (2) containing a gas reservoir (12), the tubular body having a layer structure (3) with a central proton exchange membrane (5) sandwiched between diffuser layers. The gas reservoir supplies the inner diffuser layer with a reaction gas, one end of the tubular body closed by an elastically-deformable membrane (16), provided with an operating element for the discharge valve for the pressure reservoir, e.g. a metal hydride reservoir for hydrogen.
