摘要： A co-extrusion die is configured to produce a multilayer extrusion comprising component layers of an electrochemical cell. The die comprises a plurality of inlet ports configured to receive a plurality of pressurized fluids comprising at least a first metallic ink, a second metallic ink, and a polymeric ink. A plurality of channels are configured to separately transport and shape the plurality of fluids from the plurality of inlet ports to a merge section, such that the plurality of fluids flow together in the merge section to form the multilayer extrusion comprising a polymeric membrane layer disposed between and in contact with a first metallic layer and a second metallic layer. A thickness of each layer within the merge section is controllable by adjustment of a pressure of the plurality of pressurized fluids. An outlet port is configured to output the multilayer extrusion onto a substrate.

摘要： A process for producing an ion exchange membrane involves melt-processing a mixture of a perfluorosulfonic acid ionomer in its acid form and a specific azole additive. The additive may be a triazole, alkyl triazole, vinyl triazole, fluoro-alkyl triazole, fluoro-vinyl triazole, pyrazole, alkyl pyrazole, vinyl pyrazole, fluoro-alkyl pyrazole, fluoro-vinyl pyrazole, benzimidazole, alkyl benzimidazole, vinyl benzimidazole, fluoro-alkyl benzimidazole, fluoro-vinyl benzimidazole or any mixture thereof to form a film having a thickness of from 3 to 200 microns. Ion exchange membranes so produced have reduced in-plane-swelling, improved dimensional stability and mechanical properties, and are useful as electrolytes in proton exchange membrane fuel cells.

摘要： Simplified methods for preparing a catalyst coated membrane (CCM) for solid polymer electrolyte fuel cells. The CCM has two reinforcing, expanded polymer sheets and the methods involve forming the electrolyte membrane from ionomer solution during assembly of the CCM. Thus, the conventional requirement to obtain, handle, and decal transfer solid polymer sheets in CCM preparation can be omitted. Further, CCM structures with improved mechanical strength can be prepared by orienting the expanded polymer sheets such that the stronger tensile strength direction of one is orthogonal to the other. Such improved CCM structures can be fabricated using the simplified methods.
