ABSTRACT:
A fuel cell sub-assembly includes first and second flow field plates each comprising several fastener apertures defined at a number of fastening locations. A membrane electrode assembly is situated between the first and second flow field plates and includes several fastener apertures defined at a number of fastening locations, the respective fastener apertures aligned to define fastening holes. A form-in-place fastener formed of an elastomeric material is disposed in each of the fastening holes. The elastomeric material facilitates volumetric displacement of the form-in-place fasteners in response to placing the fuel cell sub-assembly in compression.
