A　Re-C　cell　of　hybrid　structure　was　constructed　by　direct　eutectic　filling　methods,　and　realized　with　the　HTFP　experimental　system.　The　Re-C　cell　was　evaluated　according　to　CCT-WG5-WP2,　which　mainly　focus　on　construction　of　HTFP　cells　for　definitive　thermodynamic　temperature　measurements,　and　the　results　shows　that　the　short　term　repeatability　of　the　melting　temperature　was　3　mK,　and　the　difference　between　the　start　and　end　of　melting　temperature　was　198mK,　which　were　both　better　than　the　CCT　reference　values.
