The task is complicated by the fact that the control must be carried out in a vacuum environment and at low temperatures. Under such conditions, known leak sensors, as a rule, are not operable. To solve an urgent problem, the inventor Gusev A.L. A leakage sensor based on palladium manganese dioxide (PMD) was proposed, which has a protective permeable fire-retardant shell and a number of its modifications. Palladium manganese dioxide provides a hydrogen oxidation reaction with heat release at temperatures up to cryogenic. The MnO2 system has the maximum oxygen supply of all known oxides. The promotion of manganese dioxide granules by palladium nanoclusters ensures the reaction proceeds with a minimum activation energy in the low temperature zone. The released water freezes out on the cryogenic surfaces of the vacuum cavity structure. Fixation of the temperature increase in the sensor volume is provided by a thermocouple. To optimize the substance and, in fact, the design of the sensor in the course of the work, a preliminary computer simulation of the operation of a hydrogen leakage thermosensor based on PMD was carried out.Graphic abstract: Model of thermochemical sensor with quartz protective membranes "Pea 1580-002" (Author: A.L. Gusev).In the course of computer simulation in the ANSYS environment, the following were determined: the optimal dimensions, the optimal design and shape of the sensor, and also the optimal time intervals for the sensor response were determined. The experimental samples were tested in a specially designed research stand at low temperatures and high vacuum in a wide range of temperatures, pressures and hydrogen concentrations.When a 1% hydrogen mixture was supplied (air + hydrogen at N.C.), the temperature of the sensor substance in the sensor design correlated with the calculated one and was 72 degrees Celsius. The developed designs and method of application were patented and proposed for implementation to control hydrogen leaks in the vacuum cavities of cryogenic tanks and pipelines with superinsulation. The sensor substance for different applications can be made with different degrees of sensitivity and time of active functioning. The warranty period of the proposed sensor is 2 years. After an emergency operation of the sensor, it is recommended to replace it for reliable further use. In order to prevent palladium oxidation during routine (repair) work in vacuum cavities, it is recommended to protect the sensor with hydrogen-permeable membranes or vacuum safety valves.The results of the study and the specific developed hydrogen sensors are supposed to be used to increase the degree of safety at nuclear power plants, hydrogen main pipelines, in explosive and hazardous industries. They are very needed in large cryogenic complexes, in road and air transport using hydrogen as a fuel.During the implementation of the ISTC # 1580 project, the project participants conducted research and a comprehensive analysis of the possibility of using the invention of A.L. Gusev to ensure the safety of cryogenic and conventional storage and transportation systems for liquid and gaseous hydrogen.Within the framework of cooperation with European universities: University Union Nikola Tesla, Faculty of Business and Industrial Management Belgrade Serbia, as well as Pan-European University Aperion, Banja Luka BiH; Professional learing center, Belgrade, Serbia and College of Economics and Public Administration Belgrade, Serbia, additional mathematical calculations were performed - computer simulation of a hydrogen leakage thermosensor based on manganese dioxide palladium in the superinsulation of a cryogenic hydrogen tank in order to further commercialize the development in the European Union.Keywords: hydrogen leakage, cryogenic reservoir, cryogenic pipeline, superinsulation, palladium manganese dioxide, computer simulation, ANSYS software environment, palladium nanoclusters, activation energy, hydrogen concentration, reaction rate constant.
