Abstract

A vehicle includes a fuel cell system, and a controller configured to receive a first signal indicative of a predicted ambient temperature at a specified location, and command the fuel cell system to operate at a reduced relative humidity when the predicted ambient temperature is below a threshold value. A method for controlling a fuel cell system includes receiving a first signal at a controller indicative of a predicted ambient temperature for a specified location, and operating the fuel cell system at a reduced relative humidity when the predicted ambient temperature is below a threshold value. A fuel cell system includes a fuel cell stack, and a controller configured to, in response to receiving a predicted freezing condition, command the fuel cell stack to operate at a lower relative humidity level for a time period preceding a predicted time for system shut down.

Description

technical field [0001] Various embodiments relate to a system and method for preparing a fuel cell for freezing conditions. Background technique [0002] It is well known that a plurality of fuel cells are combined to form a fuel cell stack. Such fuel cell stacks typically provide electrical current in response to the electrochemical conversion of hydrogen and oxygen to water. The electrical current generated during such a process is used to drive various devices in a vehicle or other such equipment. A supply source typically provides hydrogen to the fuel cell stack. A fuel cell stack can generate electricity using less hydrogen than is provided by a supply source. An ejector receives unused hydrogen discharged from the fuel cell stack, mixes the unused hydrogen with hydrogen supplied from a supply source, and maintains a flow of hydrogen toward the fuel cell stack. [0003] During fuel cell operation, by-products such as product water and nitrogen and undepleted hydroge...
