Abstract
A heat exchange system includes a fuel cell that receives a specified gas and generates electric power, a heat exchange device that exchanges heat with a heat exchange medium, a heat exchange medium passage, and a gas detector. The heat exchange medium passage allows the heat exchange medium to circulate between the heat exchange device and the fuel cell such that the heat exchange medium can exchange heat with the heat exchange device and the fuel cell. The gas detector is disposed at at least one of the heat exchange device and the heat exchange medium passage to detect the specified gas that leaks into the heat exchange medium.
