“…It shows that dairy biogas yields the lowest power density among the tested fuels, which correlates with its lower calorific value and higher impurity content. This result agrees with another study, 33 in which lower power densities were observed in MCFCs using biogas in comparison with more conventional fuels like hydrogen due to the less efficient conversion of chemical energy into electrical energy.…”

This article presents the results of an experimental study evaluating the performance of a molten carbonate fuel cell (MCFC) using dairy biogas as a fuel source. Dairy biogas, a renewable byproduct of dairy farming, was compared with hydrogen in terms of operational efficiency. The investigation focuses on the performance parameters and efficiency metrics of MCFCs when powered by dairy biogas, relative to natural gas and hydrogen. The results demonstrate that while dairy biogas can power MCFCs, its efficiency and fuel utilization rates are lower than those of conventional fuels. This study contributes to an understanding of alternative, sustainable fuel sources for MCFC operations. During the study, the performance parameters of dairy biogas were compared with hydrogen, which served as a benchmark fuel. It was observed that in comparison with natural gas, commonly used as a fuel, dairy biogas showed lower efficiency rates and reduced fuel‐utilization factors. This suggests that although dairy biogas can be used as a fuel source for MCFCs, its effectiveness might not be on par with traditional fuels like natural gas.

“…Both the model developed by Roberts and the model developed by Gemmen are able to simulate the dynamic characteristic of the MCFC reasonably. Law [22] investigated the dynamic characteristics of the temperature gradients of the MCFC under the variation of flow types with the three-dimensional model. Lee [23] developed a three-dimensional model by using COMSOL Multiphysics software to obtain steady state conditions with the different current collectors.…”

The research on the control strategy and dynamic characteristics of the Molten Carbonate Fuel Cell-Micro Gas Turbine (MCFC-MGT) hybrid power system has received much attention. The use of the Hardware-In-the-Loop Simulation (HILS) method to study the MCFC-MGT hybrid power system, where the MCFC is the model subsystem and the MGT is the physical subsystem, is an effective means to save development cost and time. The difficulty with developing the MCFC-MGT HILS system is the transfer of the mass, energy, and momentum between the physical subsystem and the model subsystem. Hence, a new Simulation–Stimulation (Sim–Stim) interface model of the MCFC-MGT HILS hybrid power system to achieve a consistent mass, energy, and momentum with the prototype system of the MCFC-MGT hybrid power system is proposed. In order to validate the Sim–Stim interface model before application in an actual system, both a real-time model of the MCFC-MGT hybrid power system and the MCFC-MGT HILS hybrid power system based on the Sim–Stim interface model were developed in the Advanced PROcess Simulation (APROS) platform. The step-up and step-down of the current density, which were strict for the Sim–Stim interface model, were studied in these two models. The results demonstrated that the Sim–Stim interface model developed for the MCFC-MGT HILS hybrid power system is rapid and reasonable.

“…At cathode, new CO3 2− ions are formed by combing the CO2 from the anode and the O2 from the air with the two electrons from the external circuit thus closing the chemical and electrical loops [4]. In the existing literature, most investigations on MCFCs have focused on aspects including materials fabrication [5,6], further understanding of electrochemical processes and transport phenomena [7,8], stack modeling and dynamic simulation [9][10][11], and cell-based carbon dioxide capture [12,13]. Up to now, MCFCs have reached a level of maturity enough for commercialization in some countries such as USA, Germany, Japan, Italy and South Korea [14].…”
