    • A tensioner assembly that includes a base, an arm, an opening spring (i.e., a torsion spring that opens or radially expands with increasing torque applied thereto), a spring reaction member, and a pivot bushing. The tensioner assembly is configured to orient various loads in predetermined directions. For example, a spring load can be oriented to counteract a hub load to reduce a bushing load that acts on the pivot bushing. As another example, a spring reaction force exerted by the spring reaction member can be employed by a damping mechanism to generate a grounding force that is parallel to the spring reaction force and is directed to intersect an axis about which the arm pivots relative to the base. A tensioner assembly having improved assembly characteristics is also provided.

    • This invention discloses a method to enhance the lifetime of fuel cells by creating a H 2 environment for the stack, particularly in the time period from a fuel cell system stops providing power to the extemal load to the next startup, and the said H 2 environment is composed of H 2 confined within a gas-tight enclosure that is made of a material against the H 2 embrittlement. This invention discloses a device to enhance the lifetime of fuel cells; the said device consists of a gas-tight enclosure within which the stack is placed; there is an enclosure-H 2 -inlet port and an enclosure-H 2 -outlet port on the said enclosure; there is a solenoid valve before the said enclosure-H 2 -inlet port and a solenoid valve after the said enclosure-H 2 -outlet port; there are properly sized openings on the said enclosure that allow the pipelines connected to the said stack for transporting the fuel, the oxidant and the coolant respectively to pass through; the gaps between the said openings and the said pipeline are sealed. This invention prevents air from getting into the stack when the fuel cell system is in the idling or shutdown state, and therefore, it effectively solves the problems associated with the electrode damage caused by the open circuit voltage in the entire fuel cell non-operational time period and the electrode damage caused by the formation of an air/hydrogen boundary during either the startup or shutdown process of the fuel cell system. This invention also discloses methods and devices to eliminate the damages of the open circuit voltage to either MEAs or stacks during their storage time period.
