Answer: Hydrogen filling stations and the vehicles themselves on hydrogen fuel cells are equipped with standardized filling connections that meet international technical standards. These standards, among other things, ensure the required level of compatibility between filling stations and vehicles from different manufacturers. The correct operation and safety of the system is ensured by a system of mechanical locks, which allows … Continue reading Question 2: How is the separation of systems with different hydrogen pressures ensured, so that a vehicle with a maximum filling pressure of 350 bar cannot be connected to a filling system with a filling pressure of 700 bar?
