Abstract: An airflow control method of an air control system for a fuel cell stack (FCS) includes opening a recirculation valve by a controller to recirculate air through a compressor to increase a temperature of the air prior to entering the FCS to offset a FCS temperature below a predetermined threshold in response to identification to a cold-start event. The recirculation valve may be arranged with the compressor to recirculate air therethrough. The FCS may be arranged with the compressor and recirculation valve to selectively receive air therefrom. A sensor may measure thermal conditions of the FCS. The controller may be programmed to receive signals from the sensor indicating thermal conditions of the FCS, and to operate the recirculation valve based on the signals to recirculate air through the compressor to increase a temperature of the air prior to entering the FCS.

Abstract: A vehicle includes a fuel-cell system having a fuel cell, a purge valve, and a drain line extending from the purge valve. A controller is programmed to open the purge valve according to a baseline purge routine when the drain line slopes away from the purge valve, and open the purge valve according to an enhanced purge routine when the drain line slopes towards the purge valve.

Abstract: A hydrogen-water separator for a fuel cell includes an upper separation chamber having a first cylindrical sidewall defining an inlet port and a lower collection chamber configured to collect separated water. The collection chamber has a bottom and a second cylindrical sidewall defining a drain port disposed above the bottom. A divider is disposed between the separation chamber and the collection chamber. The divider spans the first cylindrical sidewall and defining one or more openings. An outlet tube is arranged vertically in the separation chamber and having an entrance that is disposed above the divider and below the inlet port.

Abstract: A fuel cell system in a vehicle has a cathode and an anode. A compressor has an inlet and an outlet, the outlet being configured to outlet a compressed air from the compressor. A bypass line is configured to return the compressed air from the outlet to the inlet such that the air returns to the compressor in a loop. A valve is located downstream of the compressor and is operable in a plurality of modes. In a first mode, the valve is configured to block the air from the cathode and return the air via the bypass line. In a second mode, the valve is configured to direct at least some of the air to the cathode. The valve can also be configured to operate in a third mode in which the air is sent to the cathode without going through the bypass line.
