摘要： A surface film structure of a metallic bipolar plate for fuel cells and a method for producing the same are provided. The method is firstly to perform flow channel machining on a bipolar plate, then to surface grind the plate so as to remove any oxide film on the plate, to degrease the plate by dipping the plate into an alkaline solution for ultrasonic cleaning, to remove from the alkaline solution and de-ionize the plate by de-ion water, again to dip the plate into a nitric acid, to de-ionize the plate after being removed from the nitric acid, to dip the plate into pure water for further ultrasonic cleaning, and finally to arrange the plate removed from the pure water into an ECM tank for forming a surface film on the plate with both chemical and electrochemical stability. The surface film including a Cr composition of 40˜75%, an Fe composition of 10˜30%, and an Ni composition of 15˜30% provides the metallic bipolar plate superior properties in corrosion-resistance, conductivity, and roughness. For a nano-structure is also provided to the surface film, the plate is then hydrophobic and self-cleaning, and thus the surface stability and flowability can be substantially increased. Further, for the Cr composition in the surface film has been particularly increased, the corrosion resistance of the metallic bipolar plate is greatly enhanced.

摘要： The present invention relates to a belt tension adjustment mechanism for use with a device including a main body and a belt pulley set. The belt pulley set includes a belt. The belt tension adjustment mechanism includes a slab, at least two tension pulleys and a fixing element. A tight tension force and a slack tension force are exerted on the opposite sides of the belt to define a tight side and a slack side of the belt when the belt pulley set runs. A counterforce is generated from the tight side of the belt to exert on the tension pulley contacting with the tight side, the slab is moved in response to the counterforce. The slack side of the belt is suppressed by the tension pulley contacting with the slack side such that the slack tension force is adjustable.
