Nissan has released the latest development in its fuel cell technology, destined for its electric vehicles.
The Japanese manufacturer sees itself as a leader in the electric vehicle market, winning the 2011 World Car of the Year and European Car of the Year awards with its fully electric Nissan LEAF, and has now released its next-generation Fuel Cell Stack with a raft of improvements over the previous model.
In making the announcement Nissan has stated the bold aim of working towards a 'Zero Emissions society', and with its latest fuel cell it appears to accept that future power sources need to be powerful, efficient, but also with reasonable costs. It aims for the new technology to provide power for the next generation of fuel cell electric vehicles.
The structure of a fuel cell is comprised of a Membrane Electrode Assembly and seperator flow path, and improvements to both have seen Nissan improve the cell's power density to 2.5kw per litre, two and half times more than its predecessor launched in 2005. The new fuel cell is 50% smaller too, as a result of changes to the Membrane Electrode Assembly's supporting frame, and the reduction in the use of platinum in the construction of the fuel cell has reduced its cost to one sixth of the previous model.
