A fuel cell system including a fuel cell stack, separator and a scavenging reservoir. The fuel cell stack is configured to generate water and reusable fuel. The separator is downstream of and in fluid communication with the fuel cell stack. The separator is configured to separate the water from the reusable fuel. The scavenging reservoir is downstream of and in fluid communication with the separator. The scavenging reservoir is configured to receive the water from the separator. The scavenging reservoir includes an inlet portion, an outlet portion, and a middle portion positioned between the inlet and outlet portions. The middle portion includes a reservoir and a passageway extending there between. The passageway is configured to allow a fluid stream to flow there through when the reservoir is occupied by a frozen fluid.

Fuel cell purge line system

A fuel cell anode purge line includes an elongated water-scavenging body having a single inlet portion, a single outlet portion having an outlet valve, and a scavenged reservoir configured to accumulate water and fluidly connect the inlet and outlet portions so as to direct a flow of purge gas from the inlet portion through the reservoir such that the purge gas entrains the water in the flow and transfers the water towards the outlet valve.

A humidification system for a fuel cell may include a condenser configured to receive fluid output from a cathode of the fuel cell and cool the fluid to extract water from it. A heat exchanger operable to transfer heat from a heat source to an airflow flowing through the heat exchanger may also be included. When the heated airflow is brought into contact with at least some of the extracted water, the airflow is humidified prior to its entering the cathode.

Humidification system and method for a fuel cell

A fuel cell system includes a fuel cell stack, an ejector in fluid communication with the fuel cell stack and having a converging-diverging (CD) nozzle with a hydrogen feed nozzle and a recirculation conduit upstream of a throat of the CD nozzle, and a thermal source configured to heat the ejector. A hydrogen supply assembly for a fuel cell system includes an ejector having a converging-diverging (CD) nozzle and a mixing chamber upstream of the CD nozzle. The mixing chamber has a recirculation conduit and a hydrogen feed nozzle. A thermal source is configured to heat the ejector. A method of controlling a hydrogen supply device for a fuel cell includes, in response to detecting a heating condition at fuel cell start up, controlling a thermal source to heat an ejector upstream of an anode stack to prevent ice formation in the ejector.
