The invention discloses a portable-type fuel cell mounting mechanism. The portable-type fuel cell mounting mechanism comprises two vertical plates which are symmetrically arranged, wherein a pluralityof connecting rods are arranged between bottoms of the two vertical plates; the plurality of connecting rods are arranged on the same horizontal plane; a plurality of groups of fixing rods are symmetrically arranged between the two vertical plates; a containing cavity for placing a fuel cell is formed among the fixing rods, the connecting rods and the vertical plates; a fixing groove is formed inthe top end of each vertical plate; the portable-type fuel cell mounting mechanism further comprises a U-shaped fixing plate which is inversely arranged; two end parts of the U-shaped fixing plate are inserted into the two fixing grooves respectively; a buffering cushion is arranged at the inner side of the U-shaped fixing plate. By adopting the portable-type fuel cell mounting mechanism, the problems of an existing sealed type mounting shell body that the weight is great and heat dissipation is not easy to realize are solved.
