Abstract
A valve including an integrated heater that has particular application for one or more of a bleed valve, a drain valve and a pressure release valve in an anode outlet unit of a fuel cell system. The valve includes a valve body having a valve body chamber defining a valve seat. A valve tappet seats against the valve seat to close a flow channel in the valve through which a fluid flows. A ring heater is mounted within the chamber so that the fluid flows through a central opening in the ring heater, where the ring heater is in close proximity to the valve seat.
