The present invention discloses a method of efficiently manufacturing fuel cells having coated bipolar plates. The present invention contemplates the laser welding together of individual plates already having a coating thereon to form the bipolar plates that are used in a fuel cell. The laser welding of the coated plates together does not result in sensitization of the plates to a magnitude sufficient to cause an undesirable level of corrosion resistance. This result is achieved regardless of the presence of the organic coating in the region of the plates being welded and regardless of the ablating of the organic coating by the laser beam.

The invention discloses a pattern electroplating method for a microstrip circuit, wherein the pattern electroplating method belongs to the technical field of a microwave millimeter wave film mixed integrated circuit. According to the pattern electroplating method, in the microstrip circuit with relatively large number of isolated conductor patterns, an original method of combining substrate front-surface pattern electroplating and back ground-surface integral electroplating is changed to a double-surface pattern electroplating process so that a medium layer at a cutting channel position is exposed to outside, thereby effectively preventing film layer falling in cutting the microstrip circuit, improving cutting quality and yield rate of the microstrip circuit, and settling a problem of film layer warpage and falling caused by stress influence to an electroplating functional layer of the microstrip circuit in a loading process and a discharging process of the electroplating protecting layer on the cutting channel in manufacture according to an existing process. According to the pattern electroplating method, electroplating deposition of the functional layer is only performed on the conductor pattern areas on the front surface and the back surface of an array circuit, thereby preventing plating of noble metals such as gold on other areas such as cutting channels and process edges outside the array pattern, reducing electroplating area and saving cost.

A chamber has a wall surface fitted with a liner. The liner is removably provided to the chamber with no fixed relation therebetween. By simply opening a light source to remove a heat diffusion plate, a hot plate and a tubular member from the chamber, the liner can be easily detached accordingly from the chamber. When a semiconductor wafer cracks to litter the chamber with its fragments, the chamber can be easily cleaned by simply detaching the liner. The liner has an outer surface subjected to surface roughening by honing. When a flash lamp emits flashlight of considerably high intensity, the roughened outer surface of the liner serves to block this flashlight. As a result, the metal surface inside the chamber is prevented from being exposed to the flashlight emitted from the flash lamp.
