Hydrogen gas under normal pressure cannot be efficiently stored and transported, and pressurization of hydrogen gas is a necessary condition in the application process. An ionic liquid hydrogen compressor has high reliability and is verified and widely applied to application scenarios such as hydrogen pipeline transportation and hydrogen filling stations. However, the prior art has the problems of poor expansibility, low space utilization, high manufacturing cost and high maintenance cost. The poor expansibility is that the hydraulic pump of a five-star structure limits the number of compression modules, cannot be combined by different numbers and types of compression modules, and cannot be flexibly expanded. The low space utilization is that the number of the structure of the traditional ionic liquid compressor is fixed, and the structure cannot be flexibly combined according to different requirements to reduce the occupied space. The high manufacturing cost and high maintenance cost are due to many non-standard parts, high machining cost of the parts, long time for disassembly and maintenance.
