A pressurized fuel cell system is demonstrated to increase the power density of the system by a factor of 2 to 3 and can operate at higher temperature, leading to fewer cooling efforts needed and thus a reduction of weight, power consumption and volume of the thermal management system.

Protocols based on safety analysis, redundancy of the powertrain, auxiliary systems, tests and simulations with the final goal of a flight demonstration will provide reliability figures in support of future certification.
