Hydrogen filter and water electrolysis hydrogen production system

The utility model discloses a hydrogen filter which is applied to a water electrolysis hydrogen production system and comprises a shell and a filter element, and the shell is at least provided with a hydrogen inlet and a hydrogen outlet; a gas distribution pipe is fixed in the shell and is communicated with the hydrogen inlet; the filter element is installed in the shell and used for filtering hydrogen. The gas distribution pipe is arranged in the hydrogen filter, so that hydrogen to be filtered is uniformly fed, large impact force on the filter element is avoided, the safety and the reliability of the filter element are improved, the shutdown maintenance frequency of a system is reduced, and the maintenance cost is reduced. The utility model further discloses a water electrolysis hydrogen production system using the hydrogen filter, safe and reliable application of the filter element is guaranteed, and the shutdown maintenance frequency of the system is reduced. 本实用新型公开一种氢气过滤器，应用于电解水制氢系统，包括外壳和滤芯，外壳至少设有氢气入口和氢
