A typical operating temperature of a solid oxide fuel cell (SOFC) is quite high above 750 °C and affects the thermomechanical behavior of the cell. Thermal stresses may cause microstructural instability and sub-critical cracking. Therefore, a joint analysis by the computational fluid dynamics (CFD) and computational structural mechanics based on the finite element method (FEM) was carried out t...

Abstract-According to SECA program guidelines, solid oxide fuel cells (SOFC) will be produced in the form of 3–10 kW modules for residential use. In addition to residential use, these modules can also be used in apartment buildings, hospitals, etc., where a higher power rating would be required. For example, a hospital might require a 250 kW power supply. To provide this power using the SOFC mo...

Alternate reality games (ARGs) are a new genre of transmedia practice in which players collaboratively hunt for clues, make sense of disparate information, and solve puzzles to advance an ever-changing narrative that is woven into the fabric of the real world. This paper highlights the potential for ARGs to promote 21st-century literacy skills. We propose a meta-level framework for 21st-century...

The Alternate Reality Game genre inspires a mode of play in which the participants choose to act as if the game world was real. Jane McGonigal has argued that one of the most attractive features of an ARG is the ‘Pinnochio’ effect: at the same time that the players deeply long to believe in them, it is in reality impossible to believe in them for real. In this article, we study “Sanningen om Ma...

The advent of the Internet has been instrumental in producing new Game Based Learning (GBL) tools where education and games converge. Alternate Reality Games (ARGs) are one such GBL tool. Interactive narrative games that use the Internet as a central communications platform, ARGs challenge players to collaboratively collate a fragmented story. When used for educational purposes, Serious ARGs pr...

The main objective of this paper is testing the reliability of a two dimensional numerical model of Solid Oxide Fuel cell using COMSOL (FEMLAB 3.1) software against neural network model. In the proposed study, two layers feed forward neural network was examined for the purpose of modeling the Solid Oxide Fuel Cell (SOFC) system. The examined neural network model with one hidden layer of five no...

This paper is concerned with optimal control of grid-connected solid oxide fuel cell (SOFC) stack based on a model developed and validated in the literature. Recent studies have shown that control of SOFC is challenging due to its slow dynamics and firm operating limits. For an SOFC, while the primary objective is to supply the demand active power, it is crucial to operate fuel cell within its ...

A NiO-10YSZ/10YSZ half-cell for anode-supported solid oxide fuel cells (SOFCs) was fabricated using 3D inkjet printing and layer-by-layer laser treatment of compositions followed by thermal sintering a co-firing method. The optimal granulometric composition rheological characteristics the to fabricate NiO-10YSZ (60:40 wt.%) anode support, (40:60 functional layer (AFL), 10YSZ electrolyte were de...

The mechanical failure of solid oxide fuel cell (SOFC) components may cause cracks with consequences such as gas leakage, structure instability and reduction of cell lifetime. A comprehensive 3D model of the thermal stresses of an anode-supported planar SOFC is presented in this work. The main objective of this paper is to get an interconnect optimized design by evaluating the thermal stresses ...
