FC2G AIP stands for Fuel Cell 2nd Generation Air Independent Propulsion. It consists in a module packaged as a dedicated hull section about 8m in length and suitable for either new-build boats or modernization programs.
The long-term (land-based) test was conducted at the Naval Group site of Indret near Nantes in March, with a true submarine operational profile. The test confirmed a submerged duration of up to three weeks, the optimization of the maintenance cycle and the performance of the major components of the system.
This patrol of 18 days has been conducted in representative operational conditions such as:
- 18 days continuous electrical production from diesel oil reforming
- high pressure (compatible with maximal immersion of the submarine)
- close to submarine environmental conditions and safety requirements
- connected to submarine batteries
- controlled and monitored by only one operator as it will be on board through the Integrated Platform Management System (IPMS)
