<P>PROBLEM TO BE SOLVED: To provide a cleaning method for a fuel cell system radiator 30 capable of finishing a cleaning process within short time, and a cleaning device 300 for the same. <P>SOLUTION: The cleaning device 300 for the fuel cell system radiator is composed of: a tank 130 storing cleaning solution at its inside; a cleaning system line 100 cleaning the fuel cell system radiator 30 by passing the cleaning solution; and a cleaning system line 200 cleaning the cleaning solution stored in the tank 130. The cleaning system line is provided with a switching unit 100b switching the flow direction of the cleaning solution made to flow through the fuel cell system radiators 30α, 30β with a prescribed time interval. As the cleaning solution flows forward and backward with a prescribed time interval, the cleaning system line receives a flow in reversed direction, cleaning effect is improved by the increase of flux cleaning effect, and the period for cleaning is shortened. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
