Giner Labs Composite Bipolar Plates are carbon-composite bipolar-plate technology for PEM fuel-cell stacks, with a focus on heavy-duty vehicle applications. Giner's approach uses a graphite-loaded thermoplastic based on a high-performance polymer such as polyphenylene sulfide (PPS), with additives to support high carbon loading and carbon nanotubes to improve electrical conductivity and mechanical strength. The development targets ultra-thin, lightweight plates while maintaining the thermal, electrical and mechanical functions required inside a PEM fuel-cell stack. The continuous graphite structure is intended to provide high thermal and electrical conductivity while the composite approach addresses scalability and durability.
