摘要
In the mounting of a membrane (13) in a fuel cell, there is a great risk of damages to the membrane and problems in the sealing between membrane and electrodes occur easily. These problems have been eliminated by in situ moulding of the membrane (13) in the cell. For a cell of DMFC type, a monomer such as acrylamide can be admixed with a sulfonic acid, preferably p-chlorobenzene sulfonic acid. As a cross-linking agent, N, N' -methylene-bis- acrylamide is suitably used in combination with N,N,N',N'- tetramethylene diamine and the setting reaction is initiated by a peroxo salt, suitably ammonium persulfate. As an alternative, the membrane (13) is moulded from a soda glass melt, after which the the soda is dissolved out by acid. The membrane (13) can also be moulded from water glass admixed with titanium dioxide and after the neutralisation of the mixture the water is removed, whereby the molecules arrange themselves to form a silica net, a silica gel.
