A new synthesis method of using dehydration of sugar (sucrose) with concentrated sulfuric acid was developed to synthesize mixed oxide ceramic particles with flaky shape. The anode disks prepared from flake‐shaped NiO – YSZ particles without a pore‐forming additive exhibited uniform dispersion of NiO and YSZ and a high porosity (45.6%), leading to improved cell performance as compared with an anode prepared from conventional NiO – YSZ powder in Ni – YSZ/YSZ/LSM single cells operated with H 2 as the fuel; their maximum power densities were 381 and 300 mW·cm −2 at 850°C, respectively.
