The invention provides a top edge beam structure of a fuel cell hydrogen energy automobile. The top edge beam structure comprises a top edge beam, a top edge beam protection plate and a top cover; a seam allowance part is arranged at the upper part of the top edge beam; a bending part matched with the seam allowance part in shape is arranged at one end, connected with the top cover, of the top edge beam protection plate; the end face of the inner side of the bending part and the seam allowance part are bonded in a sealed mode through a sealing rubber strip, and the waterproof effect is achieved; a sealing strip is arranged between the outer side end surface of the bending part and the top cover, so that a waterproof effect is achieved; the interior of the top edge beam is hollow, a plurality of reinforcing ribs are arranged in a hollow cavity of the top edge beam, and the purpose of improving the bending and torsional rigidity of a vehicle body is achieved. The invention has the beneficial effects that the torsion and bending rigidity of a whole vehicle is effectively improved while the weight of the vehicle body is greatly reduced and the cost is reduced.
