1. A fuel cell mounting system comprising:
a fuel cell stack enclosure accommodating a fuel cell stack and having a flat structure, the fuel cell stack enclosure including a first flexible flange and a second flexible flange;
a support frame supporting the fuel cell stack enclosure, wherein the support frame comprises a plurality of horizontal members and a plurality of vertical members and wherein the first flexible flange and the second flexible flange extend toward the support frame; and
a connection system connecting the fuel cell stack enclosure and a vertical center of at least one of the vertical members of the support frame, wherein the connection system is configured to elastically restore the fuel cell stack enclosure to a reference position, and wherein the connection system comprises:
a band that extends from the at least one vertical member on one side of the fuel cell stack enclosure to an opposite side of the fuel cell stack enclosure;
a shaft mounted on the vertical center of the at least one of the vertical members of the support frame;
a first connection member comprising a first body rotatably mounted on the shaft, the first connection member extending in a horizontal direction to connect the first flexible flange and the support frame;
a second connection member comprising a second body rotatably mounted on the shaft, the second connection member extending in a horizontal direction to connect the second flexible flange and the support frame;
a first biasing member configured to cause the first connection member to be elastically biased toward the reference position; and
a second biasing member configured to cause the second connection member to be elastically biased toward the reference position.
