Abstract

The characteristics of high-temperature oxide fuel cells and high-temperature steam electrolysis cells under millimeter-wave irradiation were evaluated and compared with those evaluated under conventional electric furnace heating. A reversible high-temperature electrochemical cell was fabricated using alumina-dispersed zirconia as the electrolyte, lanthanum strontium manganate as the air electrode, and nickel-ziconia based cermet as the fuel one. The power generation characteristic of the fuel cell under millimeter wave irradiation was 32% higher than that of a conventional electric furnace temperature heating, and the steam electrolysis efficiency was also 120% higher under millimeter-wave irradiation than that under conventional one. Impedance measurements using an air electrode-electrolyte half-cell showed that the millimeter wave irradiation facilitated the dissociation of oxygen molecule and/or diffusion of oxygen atoms on the surface of the air electrode as well as the oxide ion conduction in the electrolyte.

使用毫米波作为外场的高温电化学装置的特性变化
对高温氧化物燃料电池和高温蒸汽电解电池在毫米波辐照下的性能进行了评价,并与常规电炉加热下的性能进行了比较。以铝分散氧化锆为电解液,锰酸锶镧为空气电极,镍锆基陶瓷为燃料电极,制备了可逆高温电化学电池。毫米波辐照下燃料电池的发电特性比传统电炉温度加热下的发电特性提高32%,毫米波辐照下的蒸汽电解效率也比传统电炉温度加热下的蒸汽电解效率提高120%。利用空气电极-电解质半电池进行的阻抗测量表明,毫米波辐照促进了氧分子的解离和/或氧原子在空气电极表面的扩散以及电解质中氧化离子的传导。
