(LSCM)在高温下具有高化学稳定性和一定的电催化活性,是目前SOEC阴极材料研究的重点.本文将LSCM材料与具有立方萤石结构的Ce_(0.8)Gd_(0.2)O_(2-δ)(GDC)材料按照摩尔比1:1混合以构造复合电极,并使用浸渍法负载不同质量分数的Ni,Cu作为金属催化剂,进一步改善LSCM材料的离子电导率和电催化活性.电极材料LSCM,电解质...
阴极材料LSCMLSCM-GDC复合电极离子电导率电化学性能高温水蒸气电解浸渍法固体氧化物电解池可以清洁,高效地将电能和热能转化为化学能,在新能源领域具有广阔的应用前景.La_(0.75)Sr_(0.25)Cr_(0.5)Mn_(0.5)O_(3-δ)(LSCM)具有较好的高温稳定性,但离子电导率相对较低,在电解过程中电催化性能不足.本文将LSCM与...
The cathode performance of LSCM/GDC composite for high temperature CO_2 electrolysis has been studied by electrochemical impedance spectroscopy (EIS) measurements in a three-electrode electrolysis cell. The main feature in the impedance of LSCM/GDC is that it showed a Gerischer like impedance ...
The enhanced electrocatalytic activity of the Pd-GDC co-infiltrated LSCM cathode compared to LSCM is attributed to the increased numbers of active triple phase boundaries and surface oxygen vacancies resulting from the co-infiltration of Pd-GDC nanoparticles on the LSCM cathode....
