In this study, we report the fabrication and performance of LSCF|BCZY|LSCF prepared by two-step modification processes which are (a) microstructure modification of LSCF by application of ethylene glycol as a dispersing agent during the synthesizing process and (b) compositional modification by introducing a small amount of proton conducting phase to extend the triple phase boundary thus accelerate the electrochemical activity of the cathodes. The electrochemical performances of the LSCF-based cathode after each modification process were monitored by an electrochemical impedance spectroscopy (EIS). The area specific resistance (ASR) of pristine LSCF cathode, modified LSCF cathode (LSCF<sub>EG<\/sub>) and composite cathode (LB30) measured at 600<sup>o<\/sup>C in the humidified air are 9.74, 1.31 and 0.47 \u2126.cm<sup>2<\/sup>, respectively. The LSCF-based button cell was found to exhibit a superior performance after undergoes the modification processes (LB30 &gt; LSCF<sub>EG<\/sub> &gt; pristine LSCF), thus proven its great potential as a promising PCFC cathode.<\/p>\n<p><strong><em>\u00a0<\/em><\/strong><\/p>\n<p><a href=\"https:\/\/drive.google.com\/open?id=1co4UnFDcVs5C2tdN5MxULEXtXiziqNvs\"><input src=\"http:\/\/abstract.i-idea.org\/wp-content\/uploads\/2018\/04\/downloadpdfbutton.png\" type=\"image\" \/> <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ismariza Ismail, Nurul Waheeda Mazlan, Lidyayatty Abdul Malik, Oskar Hasdinor Hassan, Abdul Mutalib Md Jani\u00a0and Nafisah Osman Keywords: Cathode, button&hellip;<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[10,9],"tags":[],"_links":{"self":[{"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=\/wp\/v2\/posts\/223"}],"collection":[{"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=223"}],"version-history":[{"count":1,"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=\/wp\/v2\/posts\/223\/revisions"}],"predecessor-version":[{"id":224,"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=\/wp\/v2\/posts\/223\/revisions\/224"}],"wp:attachment":[{"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=223"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=223"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/abstract.i-idea.org\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=223"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
