Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. Here we consider a direct internal reforming solid oxide fuel cell setup in which a separate fuel reformer is not required. We construct a multidimensional, detailed model of a planar solid oxide fuel cell, where mass transport in the fuel channel is modeled u...

This paper presents the performance analysis of a planar solid-oxide fuel cell (SOFC) under direct internal reforming conditions. A detailed olid-oxide fuel cell model is used to study the influences of various operating parameters on cell performance. Significant differences in efficiency nd power density are observed for isothermal and adiabatic operational regimes. The influence of air numbe...

Michigan stands at a crossroads with respect to the way that electrical vehicles (“EVs”) are sold and serviced. For many decades, Michigan—like other states—mandated cars could be serviced only through independent, franchised dealers prohibited car manufacturers from selling or servicing directly. Historically, those laws were put in place protect superior bargaining power, sometimes unfair pra...

Direct industrial application of x-ray absorption spectroscopy is demonstrated by research in catalysis (CO/H2 and naphtha reforming) and corrosion protection.

Direct Reduction processes use gases (CO and H2) for iron reduction production of sponge or direct reduced (DRI). The generation this gas occurs through methane reforming, which can be done in a reformer inside the shaft with as catalyst. latter auto-reforming processes. kinetics steam reforming catalyzed by was studied at temperatures between 875°C 1050°C. Results showed that acts catalyst con...

Owing to their high efficiency and energy density, miniaturized fuel cells are an attractive alternative to batteries in the mW-W power generation market for portable consumer and military electronic devices [cf. 1-3]. Hydrogen is being actively considered as a fuel for power generation. It can be supplied either by storage devices or its in-situ generation using reformers. However, safety and ...

In this paper, we address the conceptual design of the bioethanol process from switchgrass via gasification. A superstructure is postulated for optimizing energy use that embeds direct or indirect gasification, followed by steam reforming or partial oxidation. Next, the gas composition is adjusted with membrane-PSA or water gas shift. Membrane separation, absorption with ethanol-amines and PSA ...
