- Fuel cell-engine hybrid power generation system with parallel reformer structure

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel cell-engine hybrid power generation system that performs power generation by using a fuel cell (Fuel Cell) and an engine in combination. According to the present invention, In order to solve the problems of conventional fuel cell-engine hybrid power generation systems in which there is a problem that heat energy flowing into a reformer becomes insufficient due to generation of electricity due to operating conditions, The fuel reformer is constituted by a parallel structure of a steam reforming (SR) reformer and a partial oxidation (POX) reformer, so that the operation and operation characteristics of the PO reformer, which is an endothermic SR reformer and the exothermic reaction, The reforming is carried out through the SR reformer having high efficiency, and the heat of the SR reformer In case of abnormal operation such as the case where the heat input to the SR reformer is lower than the normal range, the POX reformer, which is capable of driving in a short time and is accompanied by an exothermic reaction, is operated to perform reforming, A fuel cell-engine hybrid power generation system having a parallel reformer structure configured to be capable of actively responding to operating conditions to maintain stable operation at all times.
