A duct system for cooling fuel cells via a coolant fluid includes a housing 100, a cooling chamber 112; an inlet port 120 configured to receive the coolant into the system; an exhaust port 130 configured to expel the coolant from the system; and a device such as a fan or impeller 138 for moving the coolant into, through, and out of the system. Preferably, the inlet and outlet ports are provided on the same face of the housing with the coolant fluid being diverted through 180 degrees to cool a fuel cell stack 14 located in the cooling chamber. A plurality of inlet ports may be provided, these being provided radially around the exhaust port. The housing may be shaped, e.g. with a ridge (180, figure 7) or curved surface (190, figure 11). The system may include a bypass chamber (168, figure 3). Valves (164, figure 3) may be provided so that the coolant passes (i) through the cooling chamber and not the bypass chamber, (ii) through the bypass chamber and not the cooling chamber, or (iii) through both the cooling and bypass chambers. The system may also be used for providing heating to fuel cells.
