Depletion of fossil fuel at an alarming rate is a major concern of humankind. Consequently, researchers all over the world are putting a concerted effort for finding alternative and renewable energy. Solid oxide fuel cell (SOFC) is one such system. SOFCs are electrochemical devices that have several advantages over conventional power generation systems like high efficiency of power generation, low emission of green house gases and the fuel flexibility. The major research focus of recent times is to reduce the operating temperature of SOFC in the range of 500 to 700 °C so as to render it commercially viable. This reduction in temperature is largely dependent on finding an electrolyte material with adequate oxygen ion conductivity at the intended operating temperature. One much material is Gadolinia doped Ceria (CGO) that shows very good oxygen ion conductivity at the intended operation temperature. The aim of this overview is to highlight the contribution that materials chemistry has made to the development of CGO as an electrolyte.

Three Dimensional Model

In this work, a three-dimensional model of a solid oxide fuel cell (SOFC) stack is developed to predict the temperature distribution across the stack. The model simulates a particular SOFC stack comprising of five single cells. Isothermal and adiabatic walls are chosen as the different boundary conditions in order to simulate the real situation, which lies somewhere in between. In the situation where adiabatic walls are assumed, the result shows that heat convection dominates the heat transfer process. However, heat conduction plays a major role when the isothermal walls are assumed. It is found that the highest temperature found in the isothermal stack is 1135 K at an operating temperature of 1073 K. The temperature difference is significant with the hottest point located in the middle of the active area. In the adiabatic stack, the temperature is at its maximum of 1574 K near the outlets of fuel and air at the same operating temperature. It should be kept in mind that both situations will have effects on the temperature behavior of the stack in reality. The temperature and current distributions of stack models in this work are also plotted in three dimensions and the analyses of stack performances are given. By comparing the results of five-cell and ten-cell stack models, the temperature differences of the five-cell stack and the ten-cell stack are 62 and 109 K, respectively. This indicates that there is a drastic temperature change throughout the stack when the stack size is increased.

Critical Issues

One of the critical issues in designing a planar solid oxide fuel cell (SOFC) is the development of materials to hermetically seal the metal (430 series stainless steel) or ceramic interconnector with the ceramic electrolyte of the cell. The main objective of this sealing material is to achieve a low leak rate, long-term stability at operating temperature and chemical compatibility with other components. One of the compositions has been operated in an SOFC in excess of 30 minutes over the range of 600, 700, 800, and 900°C. The seal is a composition of polymer blend and glass of 1:3, 1:1 and 3:1 by weight. The leakage rate of each seal was measured simultaneously under the compressive force of 100 N, 2 bar Helium. The seal was characterized using a thermogravimetric analysis. The effect of glass composition on operating temperature and compressive forces on the leakage rate have been discussed and correlated.
