- SPECIAL REPORTS
Porosity sealants are hard resins that seal microscopic leak paths in castings, graphite, ceramics and other porous substrates. Ballard wants the sealants to ensure that certain fuel cell parts are leakproof.
Ballard is working with Ford Motor Co. and DaimlerChrysler to develop low-cost, high-volume manufacturing processes for automotive fuel cells. The company's agreement with Hernon could eventually be worth up to $22 million.
