Kogenerácia je kombinovaná výroba tepla a elektrickej energie (CHP - Combined Heat and Power). Kombinovaná výroba je jeden z najlepších spôsobov ako využiť. chemickú energiu viazanú v palive. Technológie použiteľné pre kombinovanú výrobu sú: 1. spaľovacia turbína s kombinovaným cyklom, 2. protitlaková parná turbína, 3. kondenzačná parná turbína s odberom pary, 4. spaľovacia turbína s regeneráciou tepla, 5. spaľovací motor, 6. mikroturbína, 7. Stirlingov motor, 8. palivový článok, 9. Rankinove organické cykly, 10. iný typ technológie, prostredníctvom ktorej je zabezpečená kombinovaná výroba tepla a elektrickej energie.%Small micro-cogeneration units with an electrical output of about 1 kW_e and usable in detached/semidetached houses are currently available on the market. Micro-cogeneration units with natural gas based fuel cells are new, advanced, and rapidly developing types of units. Employing an oxidation-reduction reaction they directly transform the chemical energy of natural gas into electrical energy, generating heat and water as by-products. The contribution describes the measurement and evaluation of the operating parameters of a micro-cogeneration unit with a natural gas based fuel cell. Measurements have shown that the micro-cogeneration unit has the capacity to supply a household with electrical energy and also, combined with an incorporated condensing boiler, with heat.
