Direct liquid fuel cells offer many advantages of that directly converts chemical energy into electric energy for power generation with easily obtaining fuels without fuel reforming including wastes or pollutants and such oxidants like heavy metals under common conditions. This work summarizes recent advances and progress mainly on the catalysis studies and their mechanism as well as some typical examples of fuel cellâ€™s assemblies or redox pairs. The pioneering works of our laboratory indicated the technology is not only feasible but also applicable. Further investigations are required including fuel cellâ€™s output current density and applicability.
