HYDROGEN SUPPLY APPARATUS AND HYDROGEN SUPPLY METHOD

PROBLEM TO BE SOLVED: To provide a hydrogen supply apparatus and a hydrogen supply method which perform continuous supply of hydrogen generated from formic acid that is a hydrogen storage substance, while suppressing sharp rise in temperature.SOLUTION: There are provided a hydrogen supply apparatus and a hydrogen supply method, comprising: at least two hydrogen generation means to which formic acid is supplied and which generate hydrogen by a decomposition reaction of formic acid using a catalyst and supply the hydrogen to outside; heating means that is provided on each of the hydrogen generation means to heat the hydrogen generation means; and a transfer pipe that communicates at least two of the hydrogen generation means and transfers a hydrogen-containing gas that contains the hydrogen and a catalyst-containing liquid containing the catalyst in hydrogen generation means that has finished hydrogen supply from the hydrogen supply means that has finished hydrogen supply to hydrogen supply means other than the hydrogen supply means, with the hydrogen-containing gas and the catalyst-containing liquid kept in contact.SELECTED DRAWING: None 【課題】水素貯蔵物質である蟻酸から生成された水素の供給を著しい温度上昇を抑えて継続的に行う水素供給装置及び水素供給方法を提供する。【解決手段】蟻酸が供給され、触媒を用いた蟻酸の分解反応により水素生成し外部へ水素を供給する、少なくとも２つの水素生成手段と、前記水素生成手段のそれぞれに配置され、水素生成手段を加熱する加熱手段と、前記水素生成手段の少なくとも２つを連通し、かつ、水素供給を終了した水素生成手段における前記水素を含む水素含有ガス及び前記触媒を含む触媒含有液を、前記水素供給を終了した水素生成手段から該水素生成手段以外の水素生成手段へ前記水素含有ガスを前記触媒含有液と接触させて移送する移送配管と、を備えた水素供給装置及び水素供給方法である。【選択図】なし
