Abstract
In an electrolysis appliance or a reversible fuel cell which can be operated optionally as a fuel cell or as an electrolysis appliance, a gas reservoir is in the form of a one-piece or two-piece, tubular hollow body. The gas reservoir is open at the top and is split into a reservoir area and an expansion area by a separating plug having an immersion tube which passes through it and points downward. In a region of the reservoir area, the gas reservoirs are each fitted directly to the end plates, or are formed integrally with them. Each of the half-cells are connected to a respective reservoir area and to the electrolyte located in it via channels in the end plate and openings in the respective gas reservoir. The electrolysis appliances or fuel cells which are configured to have an integrated gas reservoir formed in such a way are strong and sturdy, are configured to save space, are easy to handle and can be produced at low cost.
