<P>PROBLEM TO BE SOLVED: To control temperature of an imaging apparatus using a fuel cell device as a power source so as not to damage performance of devices. <P>SOLUTION: A digital video camera using a fuel cell device 202 as a power source has a temperature sensor 316 for detecting temperature in the vicinity of a lens unit 206 and a system controller 306 for controlling operations of the fuel cell device 202 based on an output from the temperature sensor 316. When for example the temperature of the lens unit 206 surpasses a determination reference temperature and the remaining power of a lithium ion secondary battery 204 is above a reference remaining power, the system controller 306 closes a control valve 310 and stops supply of fuel into the fuel cell 312. <P>COPYRIGHT: (C)2012,JPO&INPIT |
