A hydrogen storage unit is provided with a hydrogen storage container containing a hydrogen absorption material, and a filter portion for eliminating impurities contained in stored hydrogen gas. Thereby, the impurities are eliminated from the stored hydrogen gas in the hydrogen storage container, and the hydrogen absorption material is prevented from being poisoned by the impurities. The filter portion can be provided either inside or outside the hydrogen storage container. An adsorbent for adsorbing the impurities can be used in the filter portion. The filter portion is provided with a heating means for enhancing the elimination of the impurities adsorbed in the filter portion, and can be recovered during operation.
