    Abstract: Electrode layer pattern is applied onto a polymer electrolyte membrane (PEM) web by continuously printing with an ink containing an electro-catalyst and immediately drying. An electrode layer pattern is applied onto a polymer electrolyte membrane web by printing front and back faces of the membrane continuously in the desired pattern with the electrode layers using an ink containing an electro-catalyst and immediately drying at elevated temperature. Printing is carried out while maintaining accurate positions of the patterns of electrode layers of front and back faces relative to one another. Independent claims are also included for the following: (i) application of patterned electrode layers onto a polymer electrolyte membrane web by printing one side of the membrane continuously in the desired pattern with the electrode layers using an ink containing an electro-catalyst and immediately drying at elevated temperature; (ii) production of a membrane-electrode unit by placing, adhesive bonding or laminating gas distribution structures onto a printed polymer electrolyte membrane produced by one of the above processes; and (iii) a PEM fuel cell membrane-electrode unit produced as described above.

    Abstract: A catalytic ink comprises a dispersion of carbon particles and an organic noble metal complex in a solution of ionomer. A catalytic layer (I) on a substrate material (II) containing a proton conducting polymer (ionomer), electrically conductive carbon particles and fine particles of at least a noble metal is prepared by coating the substrate material with an ink (III). The ink (III) comprises a dispersion of carbon particles and at least on organic noble metal complex in a solution of the ionomer. The coating is dried such that the ionomer and substrate are not damaged and the complex is decomposed to form finely divided noble metal particles in an oxidation state of 0. Independent claims are included for: (i) The ink (III); (ii) a process for the production of (I) on (II) by application of (III); and (iii) drying a gas diffusion electrode for a polymer electrolyte fuel cell whereby the substrate (II) is a gas distribution structure.

    Abstract: Ink (I) containing a catalyst, an ionomer and organic solvent, for the production of membrane-electrode units for polymer-electrolyte fuel cells, in which the solvent comprises mono- or poly-hydric alcohols, glycols, glycol ether-alcohols and/or glycol ethers with an evaporation number of more than 600, preferably more than 800. An independent claim is also included for a method for the production of membrane-electrode units by coating a polymer-electrolyte membrane with ink (I) as above.

    Abstract: Metal substrates are given hard coatings by applying flexible mouldings contg. plastics (I), the hard material (II) and solder powder (III) and heating in vacuo or protective gas to the working temp. of the solder used. The novelty is that (I) is EVA, ethylene-propylene copolymers and/or butyl rubber and the moulding contains 5-40 vol.% (I) and 5-40 vol.% pores, rest (II) and (III). Pref., the moulding contains 40-70 vol.% (II) or (III), 10-25 vol.% (I) and 15-35 vol.% pores. The substrate is covered first with a (II) moulding and then a (III) moulding.
