In this paper, a biogas fuelled power generation system is considered. The system is based on a molten carbonate fuel cell stack for electricity generation, coupled with a PSA for hydrogen production. The power generation system is about 500 kW and consists of a fuel cell integrated with a micro gas turbine and a steam reformer. A design model of the system is presented. A thermoeconomic analysis is performed with the objective of highlighting the critical processes in terms of low efficiencies or high cost of components and to improve the initial design. The main design parameters affecting the critical process are identified and a system optimization is performed in order to minimize the unit cost of electricity produced by the system. The analysis presented here is the first result of a three year project (BIOH2POWER), which aims to produce and test the system.

Abstract As a clean and efficient power generation device, molten carbonate fuel cell(MCFC)can directly convert chemical energy into electrical energy at the operating temperature of 650 degrees, avoiding the heat loss caused by the Carnot cycle, and effectively reducing the emission of CO2 and other pollutants. This paper introduces the background, basic principle, system design and current situation of fused carbonate fuel cell at home and abroad, and explains the technical problems that molten carbonate power generation technology is facing. At the same time, the cost of the molten carbonate power generation system is analyzed, and the present cost and the cost after industrialization are compared and evaluated to provide a reference for the economy of the molten carbonate fuel cell power generation system.

Abstract In order to solve the problems of the preparation and matching characteristics of key materials in the development of large area and large power molten carbonate fuel cell(MCFC) stack, the assembly and test operation method of 10 kW MCFC stack is proposed. In this paper, the preparation method of matrix and electrode for large area MCFC is proposed. A 10 kW class MCFC power generation system with 120 cells and an effective area of 0.2 m2 for each cell is assembled and operated. In the constant voltage discharge test, the maximum output power is 16.51kw and the current density is greater than 95 mA/cm2. In view of many experiments and analysis, an effective online evaluation method for the baking effect of MCFC electrolyte matrix is obtained, which makes the matrix, electrode and molten salt electrolyte in the molten carbonate fuel cell body form a good match, which has an important guiding significance for improving the assembly and long-term operation of MCFC battery stack. The development and performance test method of the MCFC stack in this paper will provide effective theoretical and experimental guidance for the subsequent development of the larger MCFC power generation system, which is of great significance to promote the commercial demonstration and promotion of MCFC.

Development of a molten carbonate fuel cell (MCFC) has entered the next stage of evolving into commercialization. IHI has been taking part in the Phase III MCFC Development Program in Japan started in 2000. This program has the following development plans. (1) 300 kW class pressurized MCFC power generation system combined with micro Gas turbine. (2) High-pressurized operation technologies and modularization technologies of MCFC which become indispensable to realization of medium- to large-scale MCFC - Gas turbine combined power generation system. At the first step of MCFC commercialization, these systems will be introduced into several hundreds kW cogeneration and several MW distributed power resources. In the future, MCFC will be introduced as substitution of the thermal power plants.

Pressure Swing

In this paper, a biogas fuelled power generation system is considered. The system is based on a molten carbonate fuel cell (MCFC) stack integrated with a micro gas turbine for electricity generation, coupled with a pressure swing absorption system (PSA) for hydrogen production. The aim of this work is the optimal design of the system plant considering thermodynamic and economic objective functions. The procedure starts from system decomposition in two parts: the heat transfer network and the other components (in the following indicated as the “power components”). Design parameters are the pressure ratio, some operating temperatures and mass flow rates. For each set of the design parameters, the corresponding thermodynamic conditions of flows entering and exiting the power components are obtained. Then the heat flux recovered in the heat transfer network and the primary energy consumption are determined. Economic analysis is performed by considering function costs for the power components and a relation between the heat transfer network cost and the main energy requirements. The latter is obtained through analysis of a few heat transfer network configurations.
