FUEL CELL SYSTEM: abstract simplified (18191927)

• This abstract for appeared for 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 opening degree of the hydrogen gas supply passage, while the pressure sensor detects the pressure in a downstream supply passage. The control circuit is responsible for controlling the solenoid valve. It performs two main functions: first, it detects and stores the conducted electric current and pressure at multiple points while changing the electric current at a certain speed; second, it repeats this process at a different speed.

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.
