Title:
FUEL CELL SYSTEM AND HYDROGEN PUMP FOR FUEL CELL
Document Type and Number:
Japanese Patent JP2022111689
Kind Code:
A
Abstract:
To suppress intrusion of hydrogen from a gear chamber into a motor chamber.SOLUTION: When a fuel cell hydrogen pump 10 is in operation, in a fluid circuit C1, while a pair of synchronous gears P1 rotates, the pair of synchronous gears P1 allows cooling water discharged from a discharge port 61 to reflux to a suction port 60 without passing through a motor chamber 23. Therefore, even when hydrogen enters a gear chamber 24 from a rotor chamber 25, the hydrogen is discharged to the fluid circuit C1 together with the cooling water discharged from the gear chamber 24 through the discharge port 61 to the fluid circuit C1.SELECTED DRAWING: Figure 1
