METHOD OF DISTRIBUTING POWER IN FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17961487 titled 'METHOD OF DISTRIBUTING POWER IN FUEL CELL SYSTEM
Simplified Explanation
The abstract describes a method for distributing power in a fuel cell system consisting of multiple fuel cell stacks. Here is a simplified explanation of the abstract:
- The method involves a controller determining the total power demand of the fuel cell system.
- The controller also determines the operation order of the fuel cell stacks based on their current state.
- The number of fuel cell stacks to be operated is determined based on the total power demand and the average available power of the stacks.
- The operation target fuel cell stacks are determined based on the operation order and the number of stacks to be operated.
- The power demand of each operation target fuel cell stack is determined based on the total power demand and the effective catalyst reaction area ratio of each stack.
Potential applications of this technology:
- Fuel cell systems in various industries such as automotive, aerospace, and stationary power generation.
- Hybrid power systems combining fuel cells with other energy sources.
Problems solved by this technology:
- Efficient distribution of power in a fuel cell system with multiple stacks.
- Optimizing the operation of fuel cell stacks based on their current state and power demand.
Benefits of this technology:
- Improved overall system efficiency by distributing power effectively.
- Enhanced performance and longevity of fuel cell stacks by considering their individual characteristics.
- Flexibility in adapting to varying power demands and stack conditions.
Original Abstract Submitted
A method of distributing power in a fuel cell system including a plurality of fuel cell stacks, includes determining, by a controller, a total system power demand, which is a power demand of the fuel cell system, determining an operation order of the fuel cell stacks based on a state of the fuel cell stacks, determining the number of operation fuel cell stacks among the plurality of fuel cell stacks based on the total system power demand and an average available power of the fuel cell stacks, determining operation target fuel cell stacks based on the operation order of the fuel cell stacks and the number of operation fuel cell stacks, and determining a power demand of each of the operation target fuel cell stacks based on the total system power demand and an effective catalyst reaction area ratio of each fuel cell stack included in the operation target fuel cell stacks.
