Abstract

V diplomskem delu je predstavljeno delovanje gorivne celice, različni tipi gorivnih celic, njihova medsebojna primerjava glede na izkoristek, temperaturo obratovanja, uporaba elektrolita, vrste goriva in cene. Opisana je trdno oksidna gorivna celica in priprava goriva iz zemeljskega plina. Podanih je več načinov pridobivanja vodika iz zemeljskega plina. V eksperimentalnem delu je uporabljeno parno reformiranje zemeljskega plina. Gorivne celice imajo višji izkoristek od klasičnih naprav za proizvodnjo električne energije, učinkovitost pa lahko še povečamo z uporabo termoelektričnih materialov. Namen diplomske naloge je priprava goriva za trdno oksidno gorivno celico. V nalogi je uporabljen program za simulacijo procesov Aspen Plus V10, s pomočjo katerega sta prikazani dve simulaciji za pripravo goriva iz zemeljskega plina z različnim vstopnim tlakom. Pri reformiranju iz zemeljskega plina poleg vodika pridobimo še en uporaben produkt - ogljikov dioksid. Rezultati kažejo, da pridobimo večjo količino želenih produktov pri uporabi nižjega tlaka v tokovnicah.

Secondary title:	Natural gas reforming for solid oxide fuel cells
Secondary abstract:	The diploma thesis presents the operation of a fuel cell, different types of fuel cells, their comparison in efficiency, operating temperature, use of electrolyte, type of fuel and price. Solid oxide fuel cell and fuel preparation of fuel from natural gas are described. Several methods for producing hydrogen from natural gas are given. The experimental part uses steam reforming of natural gas. Fuel cells have higher efficiency than conventional power generation devices, that can be even increased by using thermoelectric materials. The purpose of the diploma thesis is to prepare fuel for a solid oxide fuel cell. The computer simulation is performed in Aspen Plus V10 process simulation program, which provides two simulations for producing fuel from natural gas with different intel pressures. When reforming from natural gas, in addition to hydrogen, another useful product is obtained – carbon dioxide. The results show that a greater quantity of desired products is obtained by using lower pressure in stream flows.
