“…This catalyst layer was used to catalyze the reforming of hydrocarbons into H 2 and CO, thereby limiting the direct exposure of the Ni‐based anodes to the hydrocarbons. In the last ten years, numerous efforts are devoted to the development of highly active and coking resistant anode catalytic materials for SOFCs . Ye et al.…”

Solid oxide fuel cells (SOFCs) are the most widely used fuel cells due to their excellent fuel flexibility, high efficiency and low emissions. Although the liquid fuels are easier to handle and transport than hydrogen, their direct use in SOFC leads to serious performance deterioration because of the coke formation on the traditional Ni‐based cermet anodes. In this review, the advances in the development of coking resistant anodes and the new liquid fuels such as oxygenated hydrocarbons to solve the problem of coke formation with Ni‐based anodes are summarized. It is concluded that Ni‐based cermets are still the most promising anode materials and some targeted modifications are needed to improve the coking resistance. Several strategies to improve the coking resistance of Ni‐based anodes are highlighted. The aim of this review is to provide some helpful guidance and potential directions for the future design of anodes for SOFCs utilizing liquid oxygenated hydrocarbon fuels directly.

“…And, therefore, efficient catalysts are very important to improve the conversion rate of methane. In recent years, increased interests have been attracted on the biofuels, especially the bioethanol [4][5][6][7][8], which can be easily obtained from the fermentation of crops, sugar-cane, wheat and low-grade biomass such as woodchips, and bagasse [9]. Compared with methane, bioethanol has the advantage in easy storage and transportation [4].…”

Direct utilization of hydrocarbon fuels in solid oxide fuel cells (SOFCs) has drawn special attention for high energy conversion efficiency, low cost, and simple devices. However, when fueled with hydrocarbons, SOFCs encountered great difficulty in both performance and stability, which should be attributed to the sluggish hydrocarbon oxidizing reactions, the severe carbon deposition reactions, and the possible sulfur poisoning reactions in the anode. This review summarizes potential anode reactions in hydrocarbon-fueled SOFCs and discusses the possible anode deactivation mechanisms. Further, various strategies to improve the anode performance and stability are reviewed, including substituting alloys or increasing oxide basicity for nickel-based anodes, adopting oxide anodes, and adding catalyst layers. The advantages and challenges of each strategy are discussed. Special attention is paid on properties and models of novel oxide anodes, of which nano-metal catalysts are in-situ exsolved. The publications concerning SOFC anodes, mainly in recent 5 years, are listed and compared in this article.

A button‐typed single solid oxide fuel cell (SOFC) with an internal catalytic reforming layer is tested for direct‐fed ethanol SOFC technology. This catalytic functional layer consists of 5 wt% Rh/CeZrO2 catalyst and is applied in front of conventional nickel–yttria–stabilized zirconia (Ni–YSZ) anode to convert the ethanol fuel (35 vol%) into a hydrogen‐rich gas stream via the ethanol steam reforming reaction under harsh operating conditions for 24 h (steam‐to‐carbon [S/C] ratio = 3.1, 600 °C, and weight hourly space velocity [WHSV] of 176 h−1). The X‐ray powder diffraction (XRD) analysis and transmission electron microscopy (TEM) images reveal highly dispersed Rh nanoparticles with an average size of 2 nm over CeZrO2 support. Unlike the button cell without the catalytic functional layer, the electrochemical performance of the button cell with the catalytic functional layer illustrates a high coking resistance while maintaining a good power density output. The proposed SOFC with the catalytic functional layer is a viable solution for future electric cars with bioethanol‐fed SOFC technology.
