Abstract
Official abstract text for this publication.
A fuel cell stack and a compression system for providing compressive force to a fuel cell stack having first and second ends is provided. The compression system includes asymmetric leaf springs operatively connected to first and second ends of the fuel cell stack. Each leaf spring includes a slot having first and second connector positions. The compression system also includes tension members connected to the leaf springs. The tension members compress the leaf springs to provide a compressive load to the fuel cell stack.
First claim
Opening claim text (preview).
The invention claimed is: 1. A compression system for providing compressive force to a fuel cell stack having first and second ends, said compression system comprising: a first asymmetric leaf spring operatively connected to the first end of the fuel cell stack, the first leaf spring comprising: a first slot comprising a vertical opening and first and second horizontal openings with first and second connector positions at or near the ends of the horizontal openings; and first a…
