FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18447602 titled 'FUEL CELL SYSTEM
Simplified Explanation
The abstract describes a fuel cell system for a load device that includes a fuel cell, a battery, and a controller. The controller is responsible for controlling the fuel cell and the battery in order to efficiently generate electric power that meets the power demand of the load device.
- The controller calculates the accumulated electric energy generated by the fuel cell.
- It also calculates the power generation efficiency average at the time of storage of the accumulated electric energy.
- The controller determines the required power generation efficiency to meet the power demand of the load device.
- Under certain conditions, the controller either causes the fuel cell to generate electric power to meet the power demand or operates the fuel cell and battery at specific operating points to optimize power generation.
Potential Applications: - Portable electronic devices - Electric vehicles - Backup power systems
Problems Solved: - Efficiently meeting power demand of load devices - Optimizing power generation from fuel cells and batteries
Benefits: - Improved power generation efficiency - Extended battery life - Reduced environmental impact through efficient energy usage
Original Abstract Submitted
A fuel cell system for a load device may include a fuel cell, a battery, and a controller configured to control the fuel cell and the battery. The controller may be configured to: cumulatively calculate first accumulated electric energy generated by the fuel cell; cumulatively calculate a power generation efficiency average at the time of storage of the first accumulated electric energy; calculate required power generation efficiency to generate electric power that meets a power demand of the load device; under a first condition where the power generation efficiency average is lower than the required power generation efficiency, cause the fuel cell to generate electric power that meets the power demand; and under a second condition where the power generation efficiency average is higher, cause the fuel cell to generate electric power at a specific operating point and cause the battery to discharge deficient electric power.
