Title: Hydrogen purged motor for anode re-circulation blower
Inventor: SIEPIERSKI JAMES S
IPC: H01M8/04
Filed: 2002-10-24
Abstract: PROBLEM TO BE SOLVED: To disclose a fuel cell system that can be used to power a vehicle. SOLUTION: This system includes a fuel cell stack (12), which uses hydrogen and an oxidizer to generate electricity and a re-circulation loop (118) that returns unreacted hydrogen to the fuel cell stack. The system includes a hermetically sealed assembly (112) having a blower portion (116) that pressurizes hydrogen in the re-circulation loop and a motor portion (114) that drives the blower. The system also includes a source (60) of make-up hydrogen for replenishing hydrogen in the re-circulation loop. The source of hydrogen introduces make-up hydrogen in the motor portion of the assembly at a pressure greater than the pressure in the blower portion of the assembly. Consequently, make-up hydrogen flows from the motor portion of the assembly into the blower portion of the assembly where it mixes with components in the re-circulation loop.  A method of replenishing hydrogen in the fuel cell stack is also disclosed.
