Abstract:
A method for reducing the compression set of GDL during the fuel cell operation and a method for reducing the intrusion of the GDL into flow-field channels, both achieved by pre-compression preconditioning the GDL before placing it into the fuel cell. This preconditioning is performed in order to reduce the loss of compression during the life of the stack and the mal-distribution of reactant gases, and ultimately achieve the benefits of higher power output and more stable performance.
