This invention relates to a rapid disassembly and assembly method for fuel cell stacks, belonging to the field of fuel cell technology. The method uses a disassembly and assembly module composed of pull plates and lifting devices to disassemble and replace faulty battery unit modules in a fuel cell stack. Specifically, it includes the following steps: installing pull plates on adjacent modules of the faulty battery unit module; placing lifting devices on both sides of the faulty battery unit module, with the mounting surface and working surface of the lifting devices abutting against the pull plates on both sides; activating the lifting devices to drive the adjacent modules of the faulty battery unit module away from each other, leaving space between the adjacent modules for battery unit module replacement; replacing the faulty battery unit module, removing the lifting devices, and restoring the fuel cell stack. Compared with existing technologies, this invention can achieve rapid disassembly and replacement of faulty battery unit modules inside a fuel cell stack without compromising the overall pre-tightening force and airtightness of the stack.

The application discloses a development environment deployment method and device, a terminal and a storage medium, belongs to the field of software development, and utilizes operating system and architecture information to generate a basic environment identifier containing at least two layers of subordinate hierarchical fields; the identifier is matched in a global index file; when accurate matching fails, a version number and an OS type are peeled off according to a hierarchical priority to perform multi-level back-off addressing, and a configuration file path is determined; the configuration file is loaded, and depth merging is performed on array appending and object covering from low to high according to the hierarchy to generate a final configuration; a dependency and mutual exclusion relationship of a package or a task is acquired by parsing the final configuration, a directed acyclic graph is generated, and topological sorting is performed to generate a linear task sequence; the sequence is executed according to a parameter sequence by using an installation script, and mutually exclusive tasks are scheduled in a sandbox.
