METHOD FOR OPERATING A FUEL CELL SYSTEM, AND FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18552471 titled 'METHOD FOR OPERATING A FUEL CELL SYSTEM, AND FUEL CELL SYSTEM
Simplified Explanation
The invention relates to a method for operating a fuel cell system, where air is supplied to a fuel cell stack via an air intake path and outgoing air is removed via an outgoing air path. A coolant of a cooling circuit is conducted through the fuel cell stack to remove waste heat. In a starting situation, especially at freezing temperatures, the coolant is heated using at least one heat exchanger before entering the fuel cell stack, with the outgoing air used as a heat source.
- Explanation of the patent/innovation:
- Method for operating a fuel cell system - Heating coolant using outgoing air as a heat source - Utilizing heat exchangers to heat coolant before entering the fuel cell stack
Potential Applications
The technology could be applied in various industries such as automotive, aerospace, and stationary power generation.
Problems Solved
1. Efficient heating of coolant in freezing temperatures 2. Effective removal of waste heat from the fuel cell stack
Benefits
1. Improved performance and efficiency of the fuel cell system 2. Reduced energy consumption for heating coolant 3. Enhanced reliability in starting the system at low temperatures
Potential Commercial Applications
Optimized fuel cell systems for vehicles, aircraft, and power plants
Possible Prior Art
Prior art may include similar methods of heating coolant in fuel cell systems, but the specific use of outgoing air as a heat source could be a novel aspect of this invention.
