Patent abstract
A heated valve that has particular application for one or more of a drain valve, a pressure release valve and a bleed valve in an anode outlet unit of a fuel cell system. The valve includes a divided solenoid having at least two coils. During a normal operation of the valve, current is applied to both coils. During a heat-up operation of the valve, current is applied to only one of the coils so that the reduced resistance of a single coil provides increased heat.
