Enhancing the Efficiency of SOFC‐Based Auxiliary Power Units by Intermediate Methanation
TL;DR: In this paper, the authors examined attempts to further increase the system efficiency in middle-distillate-fueled solid oxide fuel cells (SOFCs) by decreasing the cathode air flow rates, based on inducing endothermic methane steam reforming inside the cells by augmenting the methane content in an upstream methanation step.

Desulfurization for Fuel Cells
TL;DR: A number of promising liquid phase sorbent capacities have been developed for desulfurization of natural gas and LPG at room temperature and low pressure as discussed by the authors, but it is not clear if a viable liquid-phase desulurization process can be developed for compact fuel processors.

Direct oxidation of hydrocarbons in a solid-oxide fuel cell
TL;DR: The observation that a solid-oxide fuel cell can be operated on dry hydrocarbons, including liquid fuels, without reforming, suggests that this type of fuel cell could provide an alternative to hydrogen-based fuel-cell technologies.

Fuel Cells - Fundamentals and Applications
TL;DR: In this paper, the authors discuss the advantages and disadvantages of both low-temperature and high temperature fuel cells and propose a modularization of fuel cells, which makes them quite flexible as the power needed can easily be attained by changing the number of modules.
