FUEL CELL SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18191927 Titled 'FUEL CELL SYSTEM'
Simplified Explanation
This abstract describes a fuel cell system that includes a fuel cell, a hydrogen gas supply passage, a solenoid valve, a pressure sensor, and a control circuit. The solenoid valve controls the flow of hydrogen gas to the fuel cell, and the pressure sensor detects the pressure in the downstream supply passage. The control circuit is responsible for controlling the solenoid valve.
The control circuit performs two main functions. First, it detects and stores the conducted electric current and pressure at multiple points while gradually changing the conducted electric current at a certain speed. Second, it repeats this process but at a different speed.
In summary, this fuel cell system uses a control circuit to monitor and adjust the hydrogen gas flow to the fuel cell based on the detected pressure in the supply passage.
Original Abstract Submitted
A fuel cell system may include a fuel cell; a hydrogen gas supply passage configured to supply hydrogen gas to the fuel cell; a solenoid valve configured to change an opening degree of the hydrogen gas supply passage; a pressure sensor configured to detect a pressure in a downstream supply passage which is a part of the hydrogen gas supply passage from the solenoid valve to the fuel cell; and a control circuit configured to control the solenoid valve. The control circuit may be configured to perform: detecting and storing a conducted electric current conducted in the solenoid valve and the pressure at plural points while changing the conducted electric current at a first sweep speed; and detecting and storing the conducted electric current and the pressure at plural points while changing the conducted electric current at a second sweep speed different from the first speed.
