摘　　要：以中间相炭微球为原料,采用凝胶注模法制备中间相炭微球(MCMB)基质子交换膜燃料电池(PEMFC)双极板。研究了分散剂、固含量和混合方式对浆料的影响以及固含量与素坯和烧结体的密度、抗弯强度的关系。结果表明:采用凝胶注模工艺,可以制备带复杂流道的中间相炭微球基双极板,且制品无缺陷,成品率高;当固含量的体积百分数从47.17%增加到58.82%时,相应的抗弯强度则从8.5MPa降低到5.8MPa;烧结后的炭制品当固含量的体积百分数从50%增加到80%时,相应的抗弯强度从11.5MPa增加到19.6MPa。Mesocarbon Microbeads-base （MCMB） bipolar plate for proton exchange membrane fuel cell was prepared by gelcasting. Also, the influence on MCMB slurry of dispersant, solid loading and mixing methods were discussed. The results suggested that gelcasting is a good technique for shaping complex MCMB base bipolar plate; the flexural strength of green bodies decreases from 8.5 MPa to 5.8 MPa with the solid loading increasing from 47.17 % to 58.82 %; The flexural strength of sintered bodies increases from 11.5 MPa to 19.6 MPa with the solid loading increasing from 50% to 80%, corresponsively.
