METHOD FOR OPERATING A FUEL CELL SYSTEM, AND CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18577994 titled 'METHOD FOR OPERATING A FUEL CELL SYSTEM, AND CONTROL DEVICE
The invention pertains to a method for operating a fuel cell system, specifically a fuel cell stack with cooling channels fed by a coolant pump. In cold conditions, the temperature of the fuel cells is indirectly measured using the pressure difference of the coolant across the stack, and the speed of the coolant pump is adjusted accordingly.
- The method involves indirectly measuring the temperature of fuel cells in a fuel cell stack by analyzing the pressure difference of the coolant across the stack.
- The rotational speed of the coolant pump is controlled based on the indirectly measured temperature to optimize performance in cold or freezing conditions.
- This innovation ensures efficient operation of the fuel cell system under varying temperature conditions.
- By adjusting the pump speed based on temperature measurements, the system can maintain optimal performance and prevent damage to the fuel cells.
- The method offers a practical solution for enhancing the reliability and efficiency of fuel cell systems in cold environments.
