Abstract: A scroll compressor for a fuel a cell which vibrates little and is compact in size. The scroll compressor includes a front housing formed integrally with a stationary scroll, a center housing molded as a unitary structure coupled to the front housing and covering at least a portion of a drive crank mechanism and a portion of a drive motor, and a rear housing coupled to the center housing and covering the rear side of the drive motor. The front housing, the center housing and the rear housing form an outer shell of the compressor. The center housing that is molded as a unitary structure helps markedly increase the rigidity as a whole, and suppresses the vibration of the scroll compressor for a fuel cell.
