ABSTRACT:
A fuel cell system is provided including a fuel cell stack having a first end and second end. The fuel cell stack includes at least one fuel cell having a membrane-electrode assembly disposed between adjacent gas diffusion layers. The fuel cell system further includes a compression retention system having a plurality of compliant straps adapted to apply a compressive force to the fuel cell stack. The plurality of compliant straps are further adapted to accommodate an expansion of the fuel cell stack during an operation thereof and maintain the compressive force within a desired range.
