Abstract
A fuel cell secondary power and thermal management system includes a compressor, a turbine, a first heat exchanger, a proton exchange membrane fuel cell, and a second heat exchanger. The first heat exchanger has first and second air flow circuits and transfers heat between the first and second air flow circuits. The proton exchange membrane fuel cell includes a cathode air flow circuit and an anode hydrogen flow circuit. The cathode air flow circuit receives air from the first air flow circuit. The second heat exchanger has a third and fourth air flow circuits and is configured to transfer heat between the third and fourth air flow circuits. The third air flow circuit receives air from the second air flow circuit outlet. The fourth air flow circuit receives the air discharged from the cathode air flow circuit and supplies air to the turbine.
