Patent number: 9174841Abstract: A nanostructured anode of solid oxide fuel cell with high stability and high efficiency and a method for manufacturing the same are revealed. This anode comprising a porous permeable metal substrate, a diffusion barrier layer and a nano-composite film is formed by atmospheric plasma spray. The nano-composite film includes a plurality of metal nanoparticles, a plurality of metal oxide nanoparticles, and a plurality of gas pores that are connected to form nano gas channels. The metal nanoparticles are connected to form a 3-dimensional network that conducts electrons, while the metal oxide nanoparticles are connected to form a 3-dimensional network that conducts oxygen ions. The network formed by metal oxide nanoparticles has certain strength to separate metal nanoparticles and prevent aggregation or agglomeration of the metal nanoparticles. Thus this anode can be applied to a solid oxide fuel cell operating in the intermediate temperatures (600˜800° C.) with high stability and high efficiency.Type: GrantFiled: August 7, 2012Date of Patent: November 3, 2015Assignee: Atomic Energy Council—Institute of Nuclear Energy ResearchInventors: Chang-Sing Hwang, Chun-Liang Chang, Chih-Ming Chuang, Chun-Huang Tsai, Sheng-Hui Nien, Shih-Wei Cheng

Patent number: 8928328Abstract: A testing device for solid oxide fuel cell (SOFC) is disclosed. The testing device which combines the original cell housing with a four-point probe equipment is set for measuring SOFC MEA. The current collectors on anode and cathode in the original cell housing are respectively replaced by four independent probe units. They are not only to collect current but also to become measuring probes. Therefore, the lateral impedance of anode and cathode can be measured. Furthermore, the local characteristics are examined by open circuit voltage (OCV), I-V curve, and electrochemical impedance spectroscopy (EIS) measurements. The results show that the lateral impedance is substantially varied with temperatures. The distributions of OCV, current density, EIS and cell voltage in long-term test at the center of the cell are different from the edge.Type: GrantFiled: January 18, 2012Date of Patent: January 6, 2015Assignee: Institute of Nuclear Energy Research Atomic Energy Council, Executive YuanInventors: Shih-Wei Cheng, Yaw-Hwa Shiu, Yung-Neng Cheng, Ruey-Yi Lee
