US 2024/0194904 A1 · SYSTEMS AND METHODS FOR OPERATING A FUEL CELL COMPRESSOR AS A COOLANT HEATER

Abstract

The present disclosure generally relates to systems and methods for operating a fuel cell system, including a coolant stream flowing through a fuel cell stack, a compressor configured to flow in a first air stream comprising a first air temperature and flow out a second air stream comprising a second air temperature, a charge cooler comprising the coolant stream configured to flow in the second air stream comprising the second air temperature, further configured to decrease the second air temperature, and flow out a third air stream comprising a third air temperature, along with a controller configured to regulate operation of the fuel cell system, including the fuel cell stack, the compressor, and the charge cooler.

Dependent claims

A fuel cell system, comprising:

a coolant stream flowing through a fuel cell stack,
a compressor including a compressor inlet and a compressor outlet, configured to flow a first air stream comprising a first air temperature into the compressor inlet and a second air stream comprising a second air temperature out of the compressor outlet, wherein the second air temperature is higher than the first air temperature,
a charge cooler including a charge cooler inlet and a charge cooler outlet, configured to flow the second air stream comprising the second air temperature into the charge cooler inlet and a third air stream comprising a third air temperature out of the charge cooler outlet, wherein the third air temperature is lower than the second air temperature, and
a controller configured to regulate operation of the fuel cell stack, the compressor, and the charge cooler.
