Nissan has developed a 70 MPa high-pressure hydrogen storage system
for the purpose of extending the driving range of fuel cell vehicles.
This newly developed high-pressure hydrogen storage tank has been certified by the High Pressure Gas Safety Instiute of Japan (KHK) as a70 MPa high-pressure hydrogen storage vessel.
The previous high-pressure hydrogen storage system compressed and stored hydrogen at a pressure of 35 MPa.
By compressing hydrogen to an even higher pressure of 70 MPa, about 30% more hydrogen can be stored in the
same tank layout space.
| System configuration and technical explanation |
 |
 |
The 70MPa high-pressure hydrogen storage tank consists of an inner aluminum liner and an outer layer of
carbon-fiber reinforced plastic (C-FPR). The C-FRP layer uses a high-strength, high-elasticity carbon fiber with an
optimally designed winding pattern. This achieves sufficient strength to withstand high pressure of 70MPa. |
