A single thermal energy storage tank is used so that costs can be reduced and an installation space can also be reduced compared to a case where two tanks, i.e., a high temperature tank and a low temperature tank are provided. In addition, the single thermal energy storage tank includes a porous block so that passage of molten salt can be more easily performed and flow pressure drop can be reduced. In addition, the porous block is configured by stacking a plurality of unit blocks so that the capacity of the single thermal energy storage tank can be easily adjusted. Furthermore, a plurality of single thermal energy storage tanks are connected in parallel so that the plurality of single thermal energy storage tanks can be selectively used according to an operation load and thus the solar thermal power generation system can easily cope with the operation load.

Disclosed is a novel cellulose electrode having high performance, which is capable of substituting for carbon paper used as a conventional fuel cell electrode. A method of manufacturing the cellulose electrode includes cutting cellulose fibers to a predetermined length and binding the fibers, or directly weaving the fibers, thus producing a cellulose sheet, directly growing carbon nanotubes on the cellulose sheet, and supporting a platinum nano-catalyst on the surface of the carbon nanotubes using chemical vapor deposition. An electrode including the cellulose fibers and use of cellulose fibers as fuel cell electrodes are also provided. As a novel functional material for fuel cell electrodes, porous cellulose fibers having micropores are used, thereby reducing electrode manufacturing costs and improving electrode performance.

Disclosed herein are a microtubular honeycomb carbon material obtained by heat-treating cellulose fiber, a production method thereof, a microtubular reactor module fabricated using the microtubular honeycomb carbon, a method for producing the microtubular reactor module, and a microcatalytic reactor system comprising the microtubular reactor module. A carbon material having a new structure is produced by heat-treating cellulose fiber, and a catalytic reactor system having a new structure is constructed by coating the surface of the carbon material with a metal catalyst. Cellulose carbide, used as the reactor material, is very simple to produce. Because it has a micro honeycomb structure having a large number of microchannels and a large number of mesopores, it can be loaded with a large amount of a catalyst compared to the prior material having the same area, and thus it is useful as a catalyst support, and the reaction efficiency can be maximized. Also, the microcatalytic reactor system can be used in applications including very small steam reformer systems that use biomass fuel such as ethanol, fuel cell reactor systems, VOC and low-concentration-hydrogen treatment systems operable below 200&#x25a1;, micro heat exchangers, and natural gas reformer systems. Thus, the invention is a useful, industrially applicable invention.
