Abstract

A hydrogen purification device including a container, a first opening structure and a second opening structure is provided. The container has at least a filter material inside. The first opening structure is disposed in the container, wherein hydrogen-rich gas mixture flows into the container via the first opening structure so that purified hydrogen gas is generated by conducting a reaction between the hydrogen-rich gas mixture and the filter material. Besides, a second opening structure is disposed in the container, wherein the purified hydrogen gas flows away from the container via the second opening structure. A fuel processor having the hydrogen purification device is also provided.
