Abstract
A system and method for cooling and humidifying a cathode subsystem of a fuel cell for an automobile. The system includes a compressor, an air input line including an intercooler configured to cool air output by the compressor, a fluid output line including a fluid injection system, a cathode stack configured to receive air via the air input line and output a fluid to the fluid output line, and an electronic processor. The electronic processor is configured to control the fluid injection system such that the fluid output from the cathode stack is injected into the air input line.
Claims10
A cathode subsystem of a fuel cell for an automobile, the system comprising:
- a compressor;
- an air input line including an intercooler configured to cool air output by the compressor;
- a fluid output line including a fluid injection system;
- a cathode stack configured to receive air via the air input line and output a fluid to the fluid output line;
- a temperature sensor;
- and
- an electronic processor configured to:
- receive, from the temperature sensor, a temperature measurement at an output of the intercooler,
- perform a comparison of the temperature measurement to a predetermined threshold, and
- control the fluid injection system such that the fluid output from the cathode stack is injected into the air input line.
A method of cooling and humidifying air provided via an air input line to a cathode stack of a fuel cell stack of an electric vehicle, the method comprising:
- receiving, from a temperature sensor, a temperature measurement at an output of an intercooler;
- performing a comparison of the temperature measurement to a predetermined threshold;
- and
- controlling a fluid injection system configured to receive fluid from a fluid output from the cathode stack such that the fluid is injected into the air input line based on the comparison.
