Hydrogenics Corp. and Dow Corning have developed a manufacturing process for sealing PEM fuel cell stacks, electrolyzers, and membrane electrode assemblies (MEA). The two companies have also agreed to jointly commercialize the technology.

The Fuel Cell "Seal-in-Place" (FCSIP) technology is an automated sealing process that injects Dow Corning's proprietary silicone materials into an unsealed assembled stack. In the development of the FCSIP technology, the expertise of Dow Corning on the collaboration of curable elastomeric seal materials and adhesive and process applications were utilized, while Hydrogenics contributed its fuel cell design engineering and testing expertise.

The Seal-in-Place process is expected to substantially reduce stack assembly time and labor costs by eliminating the need to individually seal each stack component.

"This sealing technology represents a potential breakthrough in the advancement of fuel cell commercialization," comments Joe Cargnelli, VP, Technology and co-founder of Hydrogenics. "We believe this technology will allow stack and system developers to achieve important cost reductions in fuel cell production. We also expect that the adoption of Seal-in-Place technology will lead to continuing improvements in stack performance and manufacturing processes."
