摘要： A method for shutting down a fuel cell system including operating a fuel cell stack. the method includes providing an increased cathode air flow so as to dry fuel cell membranes in the stack until a first desired level of high frequency resistance is achieved, rehydrating the cell membranes of the stack until a second desired level of high frequency resistance is achieved, and operating the stack with a decreased cathode input relative humidity until a third desired level of high frequency resistance is achieved.

摘要： A method for determining whether a fuel cell stack cooling fluid is flowing at cold fuel cell system start-up. The method monitors the temperature of the cooling fluid outside of the fuel cell stack, and determines whether the temperature of the cooling fluid is increasing properly as the temperature of the stack increases.

摘要： A method for increasing the temperature of a cooling fluid used to control the temperature of a fuel cell stack at a system freeze start-up. The method includes determining that the cooling fluid is frozen or nearly frozen, and if so, deactivating excessive power draw on the fuel cell stack to minimize stack waste heat and activating a cooling fluid heater to heat the cooling fluid. Once it is determined that the cooling fluid is not frozen or is flowing, then the method initiates a normal system start-up.

摘要： A two-step roller finger follower for shifting between high-lift and low-lift valve modes includes a body having side members defining coaxially disposed shaft orifices, a pallet end, a socket end, a slider arm aperture, and a latch pin channel. The socket end is mountable to a lash adjuster, and the pallet end is matable with a valve stem. A slider arm for engaging a high-lift cam lobe is disposed in the aperture, is pivotably mounted to the body, and includes a slider tip for engaging a latch pin having a nose section. A spool-shaped roller is adapted to follow the surface motion of low-lift cam lobes. The axis of the latch pin intersects a radius extension of the slider arm at an angle of less than 180° such that the latch pin is prevented from accidentally locking the slider arm in its lost-motion position.
