摘要: A new low temperature fuel cell based on phosphotungstic acid electrolyte was realized. The electrochemical activity investigated by polarization curves and lifetime experiments. An output electrical power of 700 mW cm−2 obtained at 25 °C 1 atm. Lifetime tests showed that the performance remained stable for prolonged periods operation (more than 300 h). influence electrokinetic mass transport parameters digital simulation galvanostatic current-potential data. Cell is mainly determined high conductivity characteristics its promoting effect towards oxygen reduction reaction.
