Single‐phase perovskite oxide SrCo 0.8 Cu 0.1 Nb 0.1 O 3– δ was synthesized using a Pechini method. X‐ray diffraction (XRD) analysis indicated a cubic structure with a =3.8806(7) Å. The oxide material was combined with active carbon, forming a composite electrode to be used as the cathode in a room temperature ammonia fuel cell based on an anion membrane electrolyte and NiCu/C anode. An open circuit voltage (OCV) of 0.19 V was observed with dilute 0.02 m (340 ppm) ammonia solution as the fuel. The power density and OCV were improved upon the addition of 1 m NaOH to the fuel, suggesting that the addition of NaOH, which could be achieved through the introduction of alkaline waste to the fuel stream, could improve performance when wastewater is used as the fuel. It was found that the SrCo 0.8 Cu 0.1 Nb 0.1 O 3− δ cathode was converted from irregular shape into shuttle‐shape during the fuel cell measurements. As the key catalysts for electrode materials for this fuel cell are all inexpensive, after further development, this could be a promising technology for removal of ammonia from wastewater.

This paper addresses energy generated in a passive anion‐exchange membrane micro fuel cell (PAEMμFC) using glycerol from several kinds of sources: high‐purity glycerol (HPG), saponification process‐derived glycerol (SPDG), crude glycerol from sunflower oil biodiesel (CGSOB) and crude glycerol from cooking oil biodiesel (CGCOB). Spectrophotometry, volumetric Karl Fischer, gas chromatography, calorimetry, Fourier transform infrared, and cyclic voltammetry were employed for the glycerol samples characterization. The PAEMμFC was tested using 0.1M glycerol of each type, achieving power densities of 1.008, 0.932, 0.871, and 0.865 mW cm−2 for HPG, SPDG, CGSOB and CGCOB, respectively. On the other hand, commercially available software from ANSYS, Inc. was used to determine the fuel velocity and pressure in the fuel reservoir and current collector as a complementary evaluation of the PAEMμFC. The results obtained for the prices of the energy of each glycerol sample were presented in order to demonstrate that the cost of energy generated through HPG is approximately 16.5 times the SPDG energy cost and 130 times the CGCOB energy cost.
