FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18591147 titled 'FUEL CELL SYSTEM
The abstract describes a fuel cell system that includes various paths for the intake and discharge of anode and cathode gases, as well as a bypass flow path, circulating pump, on-off valves, and a control device.
- Anode gas intake path linked to a hydrogen circulation path
- Anode gas discharge path connected to the anode
- Cathode gas intake path for feeding cathode gas to the fuel cell
- Cathode gas discharge path linked to the cathode
- Bypass flow path connecting the hydrogen circulation path to the cathode gas intake and/or discharge paths
- Circulating pump on the hydrogen circulation path
- On-off valves on the anode gas intake, discharge, and bypass flow paths
- Control device to manage valves and pump, controlling water discharge by rotating the pump in normal or reverse direction.
Potential Applications: - Fuel cell technology for various industries such as automotive, aerospace, and stationary power generation.
Problems Solved: - Efficient management of anode and cathode gases in a fuel cell system. - Control of water discharge through selective pump rotation.

Commercial Applications: Title: "Advanced Fuel Cell System for Enhanced Performance" This technology can be utilized in automotive vehicles, unmanned aerial vehicles, and backup power systems for commercial and residential use, leading to increased efficiency and reduced environmental impact.
Questions about the technology: 1. How does the control device manage the on-off valves and circulating pump in the fuel cell system? 2. What are the potential environmental benefits of using this advanced fuel cell system?
Original Abstract Submitted
A fuel cell system includes: an anode gas intake path that is linked to a hydrogen circulation path to feed anode gas to an anode of a fuel cell; an anode gas discharge path linked to the anode; a cathode gas intake path for feeding cathode gas to a cathode of the fuel cell; a cathode gas discharge path linked to the cathode; a bypass flow path that links the hydrogen circulation path to the cathode gas intake path and/or the cathode gas discharge path; a circulating pump on the hydrogen circulation path; on-off valves on the anode gas intake path, the anode gas discharge path, and the bypass flow path; and a control device configured to control the on-off valves and the circulating pump. The control device is configured to cause the circulating pump to rotate in a normal or reverse direction selectively to discharge water or water vapor.
