Nissan Motor Develops New Technologies for Fuel Cell Vehicles

Nissan Motor Co. of Japan has developed its first fuel cell stack and a high-pressure hydrogen storage cylinder for fuel cell vehicles (FCVs), the company announced on February 21, 2005.

Nissan achieved a substantial reduction of size and improved the performance on this fuel cell stack, the power unit of an FCV, by using various newly developed parts. While providing the same power output, the new stack is only approximately 60 percent of the previous unit's volume. Moreover, improvements in electrode materials have doubled its service life, and optimized flow of hydrogen and air inside the stack has expanded its temperature range for producing electricity.

The newly developed 70 MPa high-pressure hydrogen storage cylinder can handle double the internal pressure of earlier cylinders, increasing hydrogen storage capacity by approximately 30 percent. This technology can extend the driving range of FCVs. Nissan will start in-vehicle testing of the new technologies to further improve performance and reliability.
