An apparatus having a slidable seal and related methods to prevent leakage of hydrogen gas or other fluids in a power generator is provided. The seal can connect to a high-current conductor when slidably contacting the surface of a fluid channel formed around the conductor. The seal slidably moves relative to and maintains contact with the surface of the fluid channel. The seal preferably includes a seal body having an abrasion abatement layer of soft metal to prevent abrasions of the seal surface as it slidably moves relative to the fluid channel. The seal can include at least one sealing gasket positioned to fit within a sealing gland formed in the fluid channel. Alternatively, the seal can have at least one sealing gasket positioned in a sealing gasket formed in the seal body and an insulating gasket positioned to restrict the flow of seal-degrading electrical currents in the seal.

The valve assembly of claim 1, wherein the magnetic flux regulator has a first end portion communicating with the primary plate and has another end portion spaced from the stop. 3. The valve assembly of claim 1, wherein the magnetic flux regulator is made of magnetic conductive material. 4. The valve assembly of claim 3, wherein the magnetic flux regulator is an annular member disposed within the spool. 5. The valve assembly of claim 2, wherein the spool has a center bore for receiving a portion of the stop therein, said stop having a conductive body with a reduced area adjacent said spool. 6. The valve assembly of claim 5, wherein the stop includes a resilient insert molded into the reduced area of the conductive body. 7. The valve assembly comprising: a valve body defining a chamber with a controlled outlet; plunger reciprocably movable within the chamber to open and close the controlled outlet; a solenoid assembly operable to move the plunger upon receipt of electrical current to produce a magnetic flux having a primary path through the plunger and a secondary path bypassing the plunger. 8. The valve assembly of claim 7 further comprising means for limiting the total amount of magnetic flux produced by the electrical current.
