Patent ID: 8329352

Claim:
A fuel cell system comprising: a fuel cell stack; a first airflow generator configured to supply an airflow; a first heat exchanging module arranged between the fuel cell stack and the first airflow generator, wherein the first heat exchanging module comprises at least one heat exchanging element including: a plurality of heat exchanging units arranged to be spaced apart from one another along a first direction; and a fixing unit fixing the heat exchanging units, each of the heat exchanging units being demarcated into a first part and a second part extending from the first part by the fixing unit, wherein a thermal conductivity coefficient of each of the heat exchanging units is higher than that of the fixing unit and the fixing unit is configured to slow heat conduction between the heat exchanging units; a second heat exchanging module arranged between the first airflow generator and the first heat exchanging module, wherein the second heat exchanging module comprises at least one of the heat exchanging elements; and a flow guiding unit connecting the fuel cell stack, the first airflow generator, the first heat exchanging module and the second heat exchanging module to allow the airflow to flow through the second heat exchanging module, the first heat exchanging module, the fuel cell stack, the first heat exchanging module and the second heat exchanging module in sequence and then to flow out of the flow guiding unit, wherein the flow guiding unit has a bypass port formed in a sidewall thereof and arranged between the first heat exchanging module and the second heat exchanging module, and the bypass port is configured to guide a part of the airflow flowing from the second heat exchanging module to the first heat exchanging module out of the flow guiding unit.
