THERMOSETTING ADHESIVE SHEET AND SUB-GASKET FOR FUEL CELL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18281656 titled 'THERMOSETTING ADHESIVE SHEET AND SUB-GASKET FOR FUEL CELL
Simplified Explanation
The thermosetting adhesive sheet described in the patent application is used for sealing the periphery of a membrane electrode assembly, which consists of a solid polymer electrolyte membrane and electrodes on both sides of the membrane. The adhesive layer is made of a cured product of an adhesive composition containing a polyurethane resin with a reactive functional group and a cross-linking agent. The adhesive layer has specific properties such as a gel fraction of 60% or higher, a storage elastic modulus at 100°C of 5.0×10^3 Pa or higher and 1.0×10^3 Pa or lower, and a decreasing rate of storage elastic modulus at 120°C to the storage elastic modulus at 100°C of 0.5 or less.
- Polyurethane resin with a reactive functional group and a cross-linking agent are used in the adhesive composition.
- The adhesive layer has specific properties including a gel fraction of 60% or higher and certain storage elastic modulus values at different temperatures.
