FUEL CELLS – MOLTEN CARBONATE FUEL CELLS | Anodes

摘要: High-temperature molten carbonate fuel cells are a highly efficient and environment-friendly source of power generation for commercial industrial customers. They operate efficiently at intermediate temperatures (550–650 °C) using variety light hydrocarbon fuels such as natural gas. Nickel alloyed with small amounts aluminium and/or chromium has been widely used the anode. The desired electrochemical performance, chemical stability creep strength porous anode have demonstrated in long-endurance stack operations (>30 000 h). Parameters affecting performance endurance well understood. alternating current-impedance analyses combination gain tests current interruption technique shown that is under mass-transfer control. In contrast to cathode, less sensitive cell temperature does not approach charge-transfer limitation even low (575 °C). An advanced design balanced pore structure developed suppress or reduce mass transfer enhance lifetime. materials currently useful life >5 years. Approaches manufacturing cost, improve develop low-cost alternative tolerance high-sulfur identified.
