Metal bipolar plates
- What is a metal bipolar plate?
-
Bipolar plate for fuel cell is a key component of stacks, such as MEA (membrane electrode assembly) and GDL (gas diffusion layer) that evenly supplies hydrogen and air which are reaction gas to MEA and transfer current generated by electrochemical reaction.
SJG EV holds technologies of channel forming by thin metal material, application of gasket to maintain airtightness between components according to operation condition, and coating design to improve performance of bipolar plates including corrosion/resistance/conductivity. We are under assembly of units, inspection, evaluation, building production technologies, and mass production while pushing technology development forward with aggressive investment and support for commercialization in different fields of fuel cell in future.
