 Direct alcohol fuel cells, DAFCS, are a type of fuel cell that uses alcohol as its fuel source. They offer several advantages over traditional fuel cells, including higher energy density and easier handling of the liquid fuel. However, despite these benefits, the oxidation of polycarbon alcohols to carbon dioxide has not yet been achieved with current catalysts. This review discusses various catalysts, membranes, and operating parameters that can be used to optimize DAFC performance. This article was authored by Aline Halyu, Keith Scott, and Ulrika Krueger.
