Development of Fuel Cell Stack for New FCV 2016-01-0529

The fuel cell (FC) stack that was developed for a new FCV achieves a power density of 3.1 kW/L (one of the highest in the world) by the use of an innovative cell flow field structure, electrodes, and a simplified stack tightening structure. These innovations allow the FC stack to be installed under the floor of a sedan-type fuel cell vehicle (FCV). Underfloor installation also required excellent impact resistance, waterproofing, and rustproofing performance. These items were quantified and analyzed during the development of the FC stack, resulting in an optimized structure capable of enduring a wide range of possible underfloor inputs.
