<P>PROBLEM TO BE SOLVED: To detect a fuel concentration by utilizing detection of an optical property change of a fuel cell fuel. <P>SOLUTION: In this refraction type fuel concentration detector mainly equipped with a light source device and a photodetection device, the light source device allows a light source to enter the fuel, and the light source is refracted by the photodetection device, and thereby a plurality of optical sensors in the photodetection device can output a corresponding electric physical quantity message based on each received light quantity. Furthermore, fuel concentration information can be acquired, based on the electric physical quantity message output from each optical sensor through a circuit means and tag information from the optical sensors. <P>COPYRIGHT: (C)2008,JPO&INPIT |
