TANK DEVICE FOR TEMPERATURE PRESSURE RELIEF IN A FUEL CELL TANK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18248745 titled 'TANK DEVICE FOR TEMPERATURE PRESSURE RELIEF IN A FUEL CELL TANK
Simplified Explanation
The tank device described in the patent application is designed to provide temperature pressure relief in a fuel cell tank. It consists of at least two tank containers and a supply line that can be connected to the tank containers. Each tank container has a shutoff valve at one end, which is located between the tank container and the supply line. At the other end of the tank container, there is a safety valve. The tank containers and safety valve are enclosed by a housing element and/or encapsulated from the environment. The housing element contains a temperature-sensitive material, and a positive pressure is maintained inside it. When the pressure in the inner space decreases, the meltable medium of the safety valve melts, opening the safety valve.
- The tank device is designed for temperature pressure relief in fuel cell tanks.
- It includes at least two tank containers and a supply line.
- Each tank container has a shutoff valve at one end, and a safety valve at the other end.
- The tank containers and safety valve are enclosed by a housing element and/or encapsulated.
- The housing element contains a temperature-sensitive material.
- A positive pressure is maintained inside the housing element.
- The meltable medium of the safety valve melts when the pressure decreases, opening the safety valve.
Potential Applications
- Fuel cell technology
- Energy storage systems
- Automotive industry
- Power generation
Problems Solved
- Ensures temperature pressure relief in fuel cell tanks
- Prevents overpressure and potential damage to the tank containers
- Enhances safety in fuel cell systems
Benefits
- Simplified design for temperature pressure relief
- Efficient and reliable operation
- Increased safety in fuel cell applications
- Protection against overpressure and potential tank damage
Original Abstract Submitted
A tank device for temperature pressure relief in a fuel cell tank, the tank device comprising at least two tank containers and a supply line which can be connected to the tank containers, each of the at least two tank containers having at least one shutoff valve at one end, the shutoff valve being arranged between the respective tank container and the supply line. At least one safety valve is arranged at another end of the tank container, wherein at least the at least two tank containers and the respective safety valve are at least almost completely enclosed by a housing element and/or are encapsulated from an environment. A positive pressure prevails in the housing element, wherein the housing element contains a temperature-sensitive material, wherein the meltable medium of the safety valve melts when the pressure prevailing in the inner space falls, and thus opens the safety valve.
