FUEL CELL SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18191923 Titled 'FUEL CELL SYSTEM'
Simplified Explanation
The 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 monitors the pressure and the electric current conducted through the solenoid valve. It calculates an increase characteristic, which is the relationship between the conducted electric current and the pressure when the current increases.
Original Abstract Submitted
A fuel cell system may include: a fuel cell; a hydrogen gas supply passage; a solenoid valve that changes an opening degree of the hydrogen gas supply passage; a pressure sensor that detects a pressure in a downstream supply passage being a part of the hydrogen gas supply passage from the solenoid valve to the fuel cell; and a control circuit. The control circuit detects a rise in the pressure detected by the pressure sensor when increasing a conducted electric current conducted in the solenoid valve from a state where the solenoid valve is closed, and detection of a rising current which is the conducted electric current at a time of the rise in the pressure; and calculates an increase characteristic based on the rising current, the increase characteristic being a relationship between the conducted electric current and the pressure when the conducted electric current increases.
