A surgical instrument for supplying energy to tissue can comprise an end effector comprising a first jaw member and a second jaw member, wherein at least one of the first jaw member and the second jaw member is movable relative to the other to clamp tissue intermediate the first jaw member and the second jaw member. The instrument can further include an electrode configured to generate heat when electrical energy is supplied to the electrode and, in addition, at least one steam path within the electrode, wherein the at least one steam path is configured to vent steam generated when the tissue is heated by the electrode.
