In this paper the working principle and the different types of fuel cells are briefly presented. The typical layout of a fuel cell co-generation system is described. Some of the commercialy available systems are considered and the advantages of fuel cells are discussed. In particular an integrated plant with solid-oxide fuel cells and a gas turbine(SOFC+GT) is analysed. Some preliminary results obtained using a simulation program show that an electric efficiency of approximatively 65% can be obtained, while the First Law efficiency is over 80%Kombinirana proizvodnja električne energije in toplote(KPETH-CHP) ali kogeneracija je idealna uporaba gorilnih celic. V tem prispevku so predstavljena načela delovanja in različni tipi gorilnih celic. Podrobno je predstavljeno delovanje kogeneracije z gorilnimi celicami. Predstavljeni so nekateri komercialno uporabni sistemi in prednosti gorilnih celic. Podrobno je analiziran obrat s trdnimi oksidnimi gorilnimi celicami in plinsko turbino(TOGC in PT - SOFC in GT). Nekateri preliminarni rezultati kažejo da lahko dosežemo električni izkoristek okoli 65%, medtem ko je izkoristek po prvem glavnem zakonu nad 80%TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
