Abstract
A heat exchanging element adapted to a fuel cell system includes a plurality of heat exchanging units and a fixing unit. The heat exchanging units are arranged to be spaced apart from one another along a first direction. The fixing unit fixes the heat exchanging units. Each of the heat exchanging units is demarcated into a first part and a second part extending from the first part by the fixing unit. A thermal conductivity coefficient of each of the heat exchanging units is higher than that of the fixing unit. The fixing unit is configured to slow heat conduction between the heat exchanging units. The heat exchanging element improves a heat recovery efficiency of the fuel cell system. In addition, two kinds of fuel cell systems using the above-mentioned heat exchanging element are provided.
