This utility model relates to the field of fuel cell technology, specifically to an assembly device for an integrated fuel cell stack housing. It includes a gas port end plate, an upper end plate, and a main housing frame located at both ends of the stack core. The upper end of the gas port end plate is provided with a positioning pin that mates with a positioning hole at the bottom of the main housing frame. A first positioning guide block and a second positioning guide block are symmetrically installed on both sides of the gas port end plate. A third positioning guide block and a fourth positioning guide block are symmetrically installed on both sides of the main housing frame. A first guide rod passes through the first and third positioning guide blocks, which are coaxially arranged, and a second guide rod passes through the second and fourth positioning guide blocks, which are coaxially arranged. The through holes of the first and second positioning guide blocks are respectively interference-fitted with the first and second guide rods, and the through holes of the third and fourth positioning guide blocks are respectively slidingly fitted with the first and second guide rods. This design ensures that the housing installation does not touch the stack core, enabling low-cost assembly of the prototype stack.
