Appl. No.:

13/795115

Inventors:

Brian J. Bowers - Cambridge MA, US
Steven Fiore - Medford MA, US
Ware Fuller - Sudbury MA, US
Greg Hickey - Boston MA, US
Changsik Kim - Lexington MA, US

International Classification:

H01M 8/04

US Classification:

429435

Abstract:

A cooling system is provided for use with a fuel cell. The cooling system comprises a first heat exchanger fluidly connected to an outlet passage of the fuel cell. The first heat exchanger can be configured to condense at least a portion of a fluid passing through the outlet passage of the fuel cell into liquid water. The cooling system can also comprise a second heat exchanger fluidly connected to an outlet passage of the first heat exchanger and an inlet passage of the fuel cell. The second heat exchanger can be configured to cool a fluid passing into the inlet passage of the fuel cell. In addition, the outlet passage of the fuel cell and the inlet passage of the fuel cell can be fluidly connected to a cathode of the fuel cell, and the inlet passage of the fuel cell can be configured to supply water to the cathode.
