“…While use of methane for upgrading F‐T liquids is possible,17 the additional steps in such a process compared to MECs can potentially lead to higher costs and lower overall energy efficiency. Use of hydrogen as a fuel in PEM and other fuel cells can also result in higher energy conversion efficiencies as compared to use of methane in high temperature fuel cells20 or in turbines, etc.…”

Improving biofuel yield and water reuse are two important issues in the further development of biorefi neries. An alternative to the typical combustion-based approach to handle residual organics stream by implementation of bioelectrochemical systems such as microbial fuel cells (MFCs) and/or microbial electrolysis cells (MECs) to improve energy recovery from biomass is presented. The potential advantages of this alternative scheme in a biorefi nery include minimization of heat loss and generation of a higher-value product: electricity (in MFC) or hydrogen (MEC). The need for 5-15 gallons of water per gallon of ethanol can be reduced signifi cantly via recycling of water after MEC treatment. Removal of inhibitory byproducts such as furans, phenolics, and acetate in MFC/ MECs to generate energy, thus, has dual advantages: improvements in energy effi ciency and ability to recycle water. Conversion of the sugar-and lignin-degradation products to hydrogen is synergistic with biorefi nery hydrogen requirements for upgrading Fischer-Tropsch (F-T) liquids and other byproducts to high-octane fuels and/or high-value products. Some of these products include sorbitol, succinic acid, furan and levulinate derivatives, glycols, polyols, 1,4-butenadiol, phenolics polymers, etc. Potential process alternatives utilizing MECs in biorefi neries capable of improving energy effi ciency by up to 30% are discussed.

“…Instead, CO can be used as a fuel in an SOFC. Thus alternative fuels, like methane, methanol, and ethanol, can be used in SOFCs for power generation [11][12][13][14][15][16][17][18][19][20][21]. The fuel flexibility makes SOFCs more advantageous than hydrogen-fueled fuel cells, as it is still very difficult to produce and store hydrogen effectively and economically.…”

Electrolytic effect in solid oxide fuel cells running on steam/methane mixture

a b s t r a c tA two-dimensional model is developed to study the performance of a planar solid oxide fuel cell (SOFC) running on steam/methane mixture. The model considers the heat/mass transfer, electrochemical reactions, direct internal reforming of methane (CH 4 ), and water gas shift reaction in an SOFC. It is found that at an operating potential of 0.8 V, the upstream and downstream of SOFC work in electrolysis and fuel cell modes, respectively. At the open-circuit voltage, the electricity generated by the downstream part of SOFC is completely consumed by the upstream through electrolysis, which is contrary to our common understanding that electrochemical reactions cease under the open-circuit conditions. In order to inhibit the electrolytic effect, the SOFC can be operated at a lower potential or use partially pre-reformed CH 4 as the fuel. Increasing the inlet gas velocity from 0.5 m s −1 to 5.0 m s −1 does not reduce the electrolytic effect but decreases the SOFC performance.
