Simple membrane electrode and frame assemblies for a solid polymer electrolyte fuel cell stack and improved methods for making them are disclosed which involve the use of a single adhesive layer. Using an appropriate design, the single adhesive layer can provide multiple bonds, including a bond between one of the gas diffusion layers and a catalyst coated membrane assembly, between the catalyst coated portion of the catalyst coated membrane assembly and the frame, and between either the other of the gas diffusion layers and the frame, or between an uncoated portion of the catalyst coated membrane assembly and the frame.

Membrane electrode and frame assembly for fuel cell stacks and method for making

The invention relates to a method for manufacturing a membrane electrode assembly for a fuel cell, which membrane electrode assembly comprises a membrane () with a catalyst layer () and a frame () arranged on the same side of the membrane () and a gap () between the catalyst layer () and the frame (). To allow an easy and cost-effective way for manufacturing such a membrane assembly, the manufacturing method comprises the following steps: *- Positioning a first decal layer (), which is made of the same material as the first catalyst layer (), on the first side of the membrane () in a way that the first decal layer () overlaps the frame (), *- positioning a second decal layer (), which is made of the same material as the second catalyst layer (), on the second side of the membrane (), *- pressing the first decal layer () and the second decal layer () against each other with the membrane () and the frame () positioned in-between.

Improved additives can be used to prepare polymer electrolyte for membrane electrode assemblies in polymer electrolyte fuel cells. Use of these improved additives can not only improve durability and performance, but can also provide a marked performance improvement during initial conditioning of the fuel cells. The additives are chemical complexes comprising certain metal and organic ligand components.

Composite proton conducting electrolyte with improved additives for fuel cells

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.
