Abstract: There is provided a fuel cell mounting structure including: a pair of left and right vibration-proofing members that are provided due to front side joining portions and rear side joining portions being mounted to suspension members; and a fuel cell that is supported at least by the pair of left and right vibration-proofing members, and is disposed at vehicle body upper sides of the suspension members, wherein one of the front side joining portions and the rear side joining portions are supported so as to be rotatable with a vehicle transverse direction being an axis of rotation, and another of the front side joining portions and the rear side joining portions are structured so as to break away from the suspension members, due to weak portions breaking at a time when load is inputted to the fuel cell from a vehicle body longitudinal direction.
