Problems solved by technology

Recently, according to the so-called green house effect, which is the result of carbon dioxide discharge, a global warming phenomenon is rapidly progressing, so that a serious natural disaster occurs, thereby the existence of human beings is threatened.

The above process has been considered to be an influential method in that heat is stably supplied at a temperature of 950° C. or more and dangerousness is low.

However, the selection of the material used in an apparatus for performing the process is becoming the most important issue.

The reason is that a metal material must be used for high-temperature elasticity in the apparatus for the hydrogen producing process, but SO2 and SO3, generated at the time of thermally decomposing sulfuric acid, have extremely high corrosiveness, and thus it is difficult to establish an economical system using any metallic material that has been developed to date, and ceramic materials have excellent corrosion resistance but can be broken by thermal stress at high temperature, so that it is difficult to use such ceramic materials in the apparatus for the hydrogen producing process.

However, generally, since ceramics and metals are different from each other in the thermal expansion, the thermal conductivity, and the like, they have poor adhesiveness with each other and thus are easily separated.
