Renewable　energies　from　solar　and　wind　power　are　playing　an　ever　increasing　role　in　meeting　the　tremendous　global　energy　demand　with　substantially　reduced　carbon　emissions;　however,　their　intermittent　nature　poses　a　critical　challenge　for　sustainability　and　practical　applications.　The　capability　of　solid　oxide　cells　(SOCs)　to　operate　in　both　fuel　cell　and　electrolysis　modes　makes　them　one　of　the　most　important　candidates　for　efficient　storage　and　regeneration　of　renewable　energies.　Here　we　present　a　critical　review　and　prospects　on　the　development　of　key　fabrication　techniques,　e.g.　wet　infiltration,　exsolution　and　direct　assembly,　for　nanostructured　electrodes,　one　of　the　most　critical　issues　affecting　the　performance　and　stability　of　SOC　technologies.　The　traits　and　challenges　of　these　techniques　are　thoroughly　discussed,　with　an　aim　to　provide　a　critical　guide　for　future　design　and　development　of　more　refined,　high-performing　nanostructured　electrodes　for　SOCs.
