NOVELTY - The device comprises an electrolytic device (214) for receiving water from a water source and converting the water to hydrogen and oxygen through electrolysis. A set of heat transferring units (210) are thermally connected with the electrolytic device to assist in maintaining desired range of temperature at the electrolytic device. A set of selective conduction layers are positioned between the electrolytic device and the heat transferring units to permit heat transfer from the heat transferring units to the electrolytic device.    USE - The device is useful for generating hydrogen that is useful as a fuel for an internal combustion engine.    ADVANTAGE - The device maintains constant high working temperature at the electrolytic device by the heat transferring units and thermal insulation part. The thermal insulation part can enclose the hydrogen generating unit and prevent heat transfer between the hydrogen generating unit and the atmosphere so that the efficiency of electrolysis is increased.    DETAILED DESCRIPTION - The device comprises an electrolytic device (214) for receiving water from a water source and converting the water to hydrogen and oxygen through electrolysis. A set of heat transferring units (210) are thermally connected with the electrolytic device to assist in maintaining desired range of temperature at the electrolytic device. A set of selective conduction layers are positioned between the electrolytic device and the heat transferring units to permit heat transfer from the heat transferring units to the electrolytic device and prevent electric conduction between the electrolytic device and the heat transferring units. The device further comprises a first conduit (206) that is connected between the electrolytic device and the water source for transporting the water from the water source to the electrolytic device, where the first conduit is thermally coupled with an internal combustion engine to convert water from the water source to water vapor due to heat conduction between the first conduit and the internal combustion engine. The thermal coupling between the first conduit and the internal combustion engine is established by coupling the first conduit and an exhaust conduit of the internal combustion engine. A thermal insulation part (230) encloses the device to prevent heat transfer. The electrolytic device comprises a membrane for receiving high temperature water from the water source, a frame encloses the membrane, two metal mesh plates attached to a first side and a second side of the membrane to facilitate electrolysis of the water at the high temperature, and a set electrodes attached to the metal mesh plates, where the electrodes attract hydrogen and oxygen ions from the ceramic membrane of water when electricity is supplied. The membrane is made of a ceramic material, and the frame comprises silica and rubber. The selective conduction layers comprise a set of metal layers that are attached to the heat transferring units to conduct heat from the heat transferring units, and a set of thermal conduction layers (216) positioned between the metal layers and the electrolytic device, where the thermal conduction layers permit heat conduction and prevent electric conduction and are made of mica. An INDEPENDENT CLAIM is included for a system for generating hydrogen.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic exploded view of a device for generating hydrogen.
