Nissan Motor Co. Ltd. has released its next-generation fuel-cell stack for fuel-cell electric vehicles (FCEV).
Through improvements to the membrane electrode assembly (MEA) and the separator flow path, which make up the structure of fuel cell, Nissan says it has significantly improved the power density of the stack to 2.5 times greater than its 2005 model.
Furthermore, molding the supporting frame of the MEA integrally with the MEA enabled stable, single-row lamination of the fuel cell, thereby reducing its overall size by more than half compared to conventional models, the company notes. Additionally, compared with the 2005 model, both the usage of platinum and parts variation has been reduced to one quarter, thereby reducing cost of the stack to one-sixth of the 2005 model.
