چکیده
Objectives • Develop realistic and internally consistent detailed designs for automotive gasoline fuel processor/ proton exchange membrane (PEM) fuel cell systems and direct hydrogen PEM fuel cell systems by using current-year technology. • Apply Design for Manufacture and Assembly (DFMA) design and costing techniques to compare system designs at low, medium, and high annual production rates. • Develop a roadmap to lower system cost by performing a sensitivity study of the major components in the fuel processor and fuel cell systems. • Determine the impact on cost, volume, and mass of replacing the fuel processor unit operations with microchannel-type components.

Performance assessment of a SOFC cogeneration system for residential buildings located in eastern Iran
It is expected that residential units may replace traditional heat and power production systems with cogeneration ones. Among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. In this paper, a cogeneration system based on solid oxide fuel cells is examined. The system, including the f...

In the present study, thermo-economic analysis of a combined solid oxide fuel cell (SOFC) with a gas turbine, a generator-absorber heat exchanger (GAX) and heating process heat exchanger for heating, cooling and power production as a tri-generation system is conducted. Also, an external steam reformer is applied to convert methanol as oxygenated fuel to hydrogen for the electrochemical process ...
متن کاملNear-Optimal Controls of a Fuel Cell Coupled with Reformer using Singular Perturbation methods
A singularly perturbed model is proposed for a system comprised of a PEM Fuel Cell(PEM-FC) with Natural Gas Hydrogen Reformer (NG-HR). This eighteenth order system is decomposedinto slow and fast lower order subsystems using singular perturbation techniques that provides tools forseparation and order reduction. Then, three different types of controllers, namely an optimal full-order,a near-opti...
متن کاملWater-balance Assessment in a Reformer/Fuel-cell System
Abstract. In PEM fuel cells pure hydrogen is used as a fuel. Due to its low density, the density of its stored energy is low, too. One of the possible solutions to the problem is production of hydrogen from the energy-reach material, e.g. methanol. Conversion of methanol to hydrogen is made with reformer in a steam reforming process in which besides methanol there is also water needed. On the o...
متن کاملDevelopment of Liquid Fuel Reformer Using Low Energy Pulse (LEP) Discharge at Room Temperature
We studied steam reforming of ethanol at room temperature and atmospheric pressure using low energy pulse (LEP) discharge. In this study, we employed characteristic novel reformer, one electrode was made of carbon fibers (o.d. 7.0 μm) bundle. So fuel was supplied to discharge region by capillary action of the fibers and reformed directly by LEP plasma without any pump or heater. When using this...
