A　typical　Ni0.75Fe0.25　catalyst　was　prepared　with　different　chelating　agents,　citric　acid　(CA),　glycolic　acid　(GA)　and　D-gluconic　acid　(D-GA)　by　thermal　decomposition　method.　The　phase　structure　and　crystalline　size　of　FeNi3　phase　in　reduced　catalysts　depend　on　chelating　agents.　The　O2-TPO　profiles　and　Raman　spectra　reveal　that　the　D-GA　catalyst　has　the　best　coke　resistance　among　the　catalysts.　In　addition,　the　cell　with　the　D-GA　catalyst　layer　has　a　maximum　peak　power　density　of　289　mW·cm-2　when　operating　at　650℃　in　methane.　Moreover,　the　voltage　of　the　cell　still　remains　61%　of　the　initial　value　after　operating　in　methane　for　9　hours　under　a　current　density　of　600　mA·cm-2　at　650℃,　which　is　more　stable　than　that　of　catalyst　layer　without　chelating　agent　(53%).　©,　2014,　Editorial　Office　of　Transactions　of　Materials　and　Heat　Treatment.　All　right　reserved.
