The performance of current solid oxide fuel cells (SOFCs) was evaluated in terms of the cell designs and the physicochemical properties of the component materials such as the electrode and electrolyte in order to demonstrate the potentials of state-of-the-art SOFC technology for the widespread use of SOFCs. A flat tubular type SOFC stack for residential use was analyzed as a standard case of a production version in terms of stack volume, weight, and material cost. The power density and power generation efficiency were also evaluated by model estimation. A microtubular type SOFC was evaluated as an example of an advanced cell design. The assessment of the cell design can pinpoint performance advantages of the microtubular type in stack volume, weight, material cost, volumetric power density, and efficiency. In addition, we attempted to demonstrate an analysis for the concurrent comparison of the impact of cell designs and material properties on cell performance by using volumetric power density as a common assessment criterion. Through the assessment with the state-of-the-art SOFC technology, it is possible to make a quantitative comparison of the significances of cell design and material property. The present assessment suggests that the development of cell design is a consistent approach to improving cell and stack performance. In this way, the proposed assessment can provide hints to a reliable research strategy for improving cell performance and realizing the widespread use of SOFCs.

Direct internal reformation of methane in solid oxide fuel cells (SOFCs) leads to two major performance and longevity challenges: thermal stresses in the cell due to large temperature gradients and coke formation on the anode. A simplified quasi-two-dimensional direct internal reformation SOFC (DIR-SOFC) dynamic model was developed for investigation of the effects of various parameters and assumptions on the temperature gradients across the cell. The model consists of 64 nodes, each containing four control volumes: the positive electrode, electrolyte, negative electrode (PEN), interconnect, anode gas, and cathode gas. Within each node the corresponding conservation and chemical and electrochemical reaction rate equations are solved. The model simulates the counter-flow configuration since previous research (Achenbach, 1994, “Three-Dimensional and Time-Dependent Simulation of a Planar Solid Oxide Fuel Cell Stack,” J. Power Sources, 49(1), p. 333) has shown this configuration to yield the smallest temperature differentials for DIR-SOFCs. Steady state simulations revealed several results where the temperature difference across the cell was considerably affected by operating conditions and cell design parameters. Increasing the performance of the cell through modifications to the electrochemical model to simulate modern cell performance produced significant changes in the cell temperature differential. Improved cell performance led to a maximum increase in the temperature differential across the cell of 31 K. An increase in the interconnect thickness from 3.5 to 4.5 mm was shown to reduce the PEN temperature difference about 50 K. Variation of other physical parameters such as the thermal conductivity of the interconnect and the rib width also showed significant effects on the temperature distribution. The sensitivity of temperature distribution to heat losses was also studied, showing a considerable effect near the fuel and air inlets. Increased heat transfer from the cell edges resulted in severe temperature gradients approaching 160 K/cm. The dynamic capability of the spatially resolved dynamic model was also demonstrated for a 45% power increase perturbation while maintaining constant fuel and air utilizations.
