Abstract: A heat generating device includes a pair of heaters provided with an interval therebetween; and a plurality of heat generating elements that are capable of occluding hydrogen and generating heat using a heat generating reaction by quantum diffusion of the hydrogen caused by heat of the pair of heaters, in which the plurality of heat generating elements are arranged with an interval between each other and are arranged between the pair of heaters.

Abstract: A heat generating cell includes: a support having tubular shape; and a multilayer film formed on an inner peripheral surface of the support for generating heat by occlusion and discharge of hydrogen. A heat generating device includes: a plurality of the heat generating cells; a sealed container; a plurality of separators dividing an inside of the sealed container into a first space, a second space, and a third space in an axial direction of the sealed container, the first space and the second space being locating at both ends in the axial direction in the sealed container; and a heater for heating each of the plurality of heat generating cells. The plurality of heat generating cells penetrate through the plurality of separators, and both ends of each of the plurality of heat generating cells in an axial direction are respectively opened to the first space and the second space.

Abstract: A process for manufacturing a zeolite membrane by hydrothermal synthesis on the surface of a porous tubular support 3 with both ends open, by adding a reaction solution containing a silica source and an alumina source and the porous tubular support 3 into a lengthwise reaction container 1 longer than the porous tubular support 3 while placing the porous tubular support 3 vertically in the reaction container 1 and substantially apart from the inner surface of the reaction container 1, and immersing the porous tubular support 3 completely in the reaction solution so that the inside of the porous tubular support 3 is filled with the reaction solution; and heating the reaction solution under conditions of leaving the top and bottom ends of the porous tubular support 3 open, and an apparatus using thereof and zeolite tubular separation membranes thus obtained.
