英文摘要	Today, due to environmental crises, the interest in using alternative technologies has increased. Meanwhile, fuel cells have considerable performance and development, and their use in hybrid energy cycles has recently become very popular. The main characteristic of a fuel cell is that it is constant with time, which affects the performance and reliability of the fuel cell and consequently the hybrid process. This study's objective is to introduce and conceptual design of a novel energy process based on solid oxide fuel cell (SOFC) and thermionic (TI) and thermoelectric (TE) generators. The chemical energy in the fuel is converted to power by the SOFC. The waste heat of SOFC is absorbed by the TI to produce additional electricity. Moreover, TE is thermally coupled to the TI to produce further electricity. The TE and TI are benefited as the downstream and intermediate cycles, respectively. This idea leads to an increase in the utilization of waste heat and enhance the system efficiency. Furthermore, the energy coming from the system is stored via a relatively new energy storage system. The configuration and arrangement of the technologies used in the introduced energy cycle as well as the reported results are new and has not been studied in the previous researches. Results revealed that, the energy production system generates 578.6 W of electricity. The energy production system efficiency was 80.1%. Furthermore, assuming that the power generation system operated for 5 h, the required capacity of the storage system was 1.9 m(3). Four different scenarios are offered to design the energy production system to supply the 1 kW of electrical power.
