FUEL CELL SYSTEM: abstract simplified (18191923)

• This abstract for appeared for patent application number 18191923 Titled 'FUEL CELL SYSTEM'

Simplified Explanation

This abstract describes a fuel cell system that includes various components such as 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, and the pressure sensor detects the pressure in the downstream supply passage. The control circuit is responsible for monitoring the pressure and the electric current flowing through the solenoid valve. It calculates an increase characteristic, which is the relationship between the electric current and the pressure when the current increases. Overall, this system is designed to efficiently regulate the flow of hydrogen gas in the fuel cell.

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.
