Nissan releases next generation fuel cell stack
13 October 2011
Nissan Motor Co. has released its next generation fuel cell stack (2011 model) for fuel cell electric vehicles. Through improvements to the membrane electrode assembly (MEA) and the separator flow path, which make up the structure of the fuel cell, Nissan has significantly improved the power density of the stack to 2.5 times greater than its 2005 model and realised an automotive world’s best 2.5kW per litre.
Moulding the supporting frame of the MEA integrally with the MEA enabled stable, single-row lamination of the fuel cell, thereby significantly reducing its overall size by more than half compared with conventional models. Additionally, compared with the 2005 model, both platinum use and parts variation have been reduced to one quarter, thereby reducing the cost of this next generation fuel cell stack to one-sixth that of the 2005 model.
