Liquors can serve as an emergency fuel if they can be directly converted to electricity using a highly efficient solid oxide fuel cell (SOFC). To realize this concept, integrating a paper-structured catalyst (PSC) onto the SOFC anode is an effective solution. Shochu is a most popular distilled liquor in Japan with nominal composition of 25 vol% ethanol and 75 vol% water. In this study, the catalytic performance of a Ni-loaded hydrotalcite (HT) dispersed-PSC (Ni/HT-PSC) toward the steam reforming of ethanol (SRE) was evaluated in 500–800 °C when shochu was supplied. The H 2 production rate for a shochu produced by a continuous distillation (Shochu-25°-A) was comparable to that of a mixture of 25 vol% ethanol–75 vol% water (simulated-Shochu). However, that for a shochu produced by a single-type distillation (Shochu-25°-B) containing various types of volatile organic compounds (VOCs), including sulfur compounds, was lower in the whole investigated temperature range. The results thus indicate that Shochu-25°-A is suitable as an emergency fuel, whereas a refinement process is necessary for Shochu-25°-B. Electrochemical evaluations of electrolyte-supported cells (ESCs) with the Ni/HT-PSC applied on the anode revealed that the PSC effectively avoids coking on the anode when shochu is supplied for power generation at 750 °C. [Display omitted] • Suitability of shochu, poplar liquor in Japan, as a fuel for SOFC was investigated. • Paper-structured catalyst (PSC) was applied for steam reforming of ethanol (SRE). • Shochu with lower VOC content behaved like a mixture of pure ethanol and water. • Shochu produced by single distillation was characterized by a higher VOC content. • Sulfur-containing VOCs must be removed for both reforming and power generation.
