<p><P>PROBLEM TO BE SOLVED: To provide techniques for stabilizing the gravity center of a compressed gas module used for a fuel battery system. <P>SOLUTION: When the main rotary shaft 21a of an air compressor AC storing two rotors RT1, RT2 in its pump chamber 20 is combined with the driving shaft 25 of a motor MT, the motor MT is biased to the side of the main driving shaft 21a of air compressor AC. An intercooler IC is arranged in a dead space between the air compressor AC and the motor MT caused by the biase, and the air compressor AC, motor MT and intercooler IC are integrated together into one to form a gas compression module. In this gas compression module, its unbalanced gravity center due to weight differences between the motor MT and air compressor AC has been corrected that much equal to the weight of the intercooler IC. Also this gas compression module is compact in size, because of the effective use of the dead space. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
