Extended Data Fig. 1

a, jV and j–P curves of PCFC under hydrogen (flow rate of hydrogen: 15 ml min−1, cell 1). b, jV and j–P curves of direct-methanol PCFC at 600–350 °C. Flow rate of the mixture of methanol and water (molar ratio of water/ethanol is 1, cell 3) is 0.024 ml min−1. c, jV and j–P curves of PCFC under 10 vol% iso-C4H 10 + 20 vol% O2 + 70 vol% H2O (flow rate of iso-C4H10: 0.9 ml min−1, cell 4). d, jV and j–P curves of PCFC under 10 vol% n-C4H10 + 20 vol% O2 + 70 vol% H2O (flow rate of n-C4H10: 0.9 ml min−1, cell 5). e, jV and j–P curves of PCFC under 20 vol% C3H8 + 20 vol% O2 + 60 vol% H2O (flow rate of C3H8: 1.6 ml min−1, cell 4). f, jV and j–P curves of PCFC under 33.3 vol% natural gas (simulated natural gas with 19.5 p.p.m. H2S, flow rate of natural gas: 5 ml min−1, cell 7) + 66.7 vol% H2O. g, jV and j–P curves of PCFC under 33.3 vol% natural gas (simulated natural gas without H2S, flow rate of natural gas: 5 ml min−1, cell 7) + 66.7 vol% H2O. h, jV and j–P curves of PCFC under 33.3 vol% methane (flow rate of methane: 5 ml min−1, cell 7) + 66.7 vol% H2O. i, jV and j–P curves of PCFC under 28.5 vol% methane (flow rate of methane: 5 ml min−1, cell 8) + 71.5 vol% H2O. j, jV and j–P curves of direct-ethanol PCFC at 600 °C and 550 °C. Flow rate of the mixture of ethanol and water (molar ratio of water/ethanol is 7, cell 10) is 0.005 ml min−1.
