摘要： PROBLEM TO BE SOLVED: To provide a hydrogenating method and the device capable of more rapidly and efficiently treating a large quantity of a material to cause reaction compared to a hydrogenation method using conventional electrolytically generated hydrogen. SOLUTION: An electrolytic cell main body 1 is divided into an electrolytic section 3 and a hydrogenation section 4 by a cathode 2 made from a hydrogen occluding material and a porous hydrogen occluding body is installed in electrically contact with the cathode in the hydrogenation section. Hydrogen occluded in the cathode is not released as a gas by being occluded even if excess hydrogen is generated and is effectively utilized. Further, even when power supply to the electrode is stopped, an organic material is continued to be hydrogenated by hydrogen occluded in the cathode and then, the consumption of electric power is saved. Hydrogen is continuously generated by the electrolysis and then is never exhausted as it is in the conventional one.
