A fuel cell system includes a fuel cell stack that includes PEM fuel cells. Each fuel cell has an operating temperature of at least 120&#xb0; C. The fuel cell stack has a cathode inlet to receive a flow of ambient air and a cathode outlet to provide a cathode exhaust flow. The fuel cell system includes a fuel processing reactor that has inlet and an outlet. The inlet and outlet are in fluid communication with a catalyst that is suitable for convening a hydrocarbon into a gas that contains hydrogen and carbon monoxide. The outlet is in fluid communication with an anode chamber of the fuel cell, and the inlet of the fuel processing reactor is in fluid communication with the cathode outlet.

Integrated high temperature PEM fuel cell system

A simplified PEM fuel cell system is integrated with a fuel processor and an exhaust gas oxidizer to ensure clean emissions. The fuel cell has an operating temperature of 100&#x2013;200&#xb0; C., and utilizes reformate fuel having a carbon monoxide level greater than 1000 parts per million.

An electrical card connector for electrically coupling with an external plug, includes an insulative housing that receives a plurality of contacts and a pair of mixed latching means therein. Each mixed latching means consists of a spring bar with a protrusion extending integrally with the housing, and a metallic spring buffer disposed inside the housing. Each spring buffer includes a spring arm portion preloaded by the spring bar at a first supporting section thereof, a second supporting section formed at a free end of the spring arm portion and spaced apart from a stopper wall formed on the housing thereby constructing the spring arm portion as a cantilevered beam. After the spring bar is progressively deformed to reach a specific deformation due to the coupling between the plug and connector, the second supporting section of the spring arm portion can abut against the stopper wall to transform the spring arm portion as a simple support beam. Therefore, a maximum resilient force is exercised by the spring arm portion on the spring arm to have the protrusion suddenly snap with a notch formed on the plug so as to create a resounding audio effect to inspect the locking status between the mated connector and plug.
