本研究的目的是建立一种测量固体氧化物燃料电池（SOFC）燃料电极中氧分压的方法，以阐明SOFC中的传质机理。将由涂覆有氧化锆的铂丝制成的传感器插入燃料电极中以测量氧分压。测得的氧分压随着电流密度的增加而增加，并且在相同的电流密度下随着氢气流量的减少而增加。此外，氧分压随着操作温度的降低而降低。这些趋势与模拟结果一致。
The aim of this study is to establish a measurement method of oxygen partial pressure in fuel electrodes of solid oxide fuel cells (SOFCs) to clarify a mass transfer mechanism in SOFCs. A sensor, which was made of a platinum wire coated with zirconia, was inserted into the fuel electrode to measure the oxygen partial pressure. The measured oxygen partial pressure increased with increasing the current density and with decreasing the flow rate of hydrogen at the same current density. Also, the oxygen partial pressure decreased with decreasing the operating temperature. These trends were in agreement with those of simulation results.
