“XⅩXⅩ日本”中国科研团XⅩXⅩ日本队提出全新燃料电池数字化设计方法

  中新XⅩXⅩ日本社天津12月5日电 (记者 孙XⅩXⅩ日本玲玲)记者5日从天津大学获悉,该校焦魁教授团队通过高精度数学建模,提出了全新燃料电池数字化设计方法,可快速提出、优化燃料电池设计方案,提升电池性能、缩短研发周期并降低成本。相关论文已在国际权威期刊《能源与环境科学》发表。

  燃料电池洁净、高效、无污染的特点越来越受到关注。尤其氢燃料电池,因其零污染、高效率的特质,已逐渐应用于公共交通、商用车辆、船舶等场景。但受制于成本,相关产业链尚未大展拳脚。

  “合理的燃料电池结构设计应该做到促进内部气体传输、热量耗散以及液态水排出,从而提升电池性能。”据焦魁教授介绍,目前,相关厂商既缺少商用燃料电池的高效高精度仿真模型与数字化辅助设计手段,又缺乏创新性的电池设计方案,这给燃料电池功率密度提升与成本控制造成了阻碍。“研究燃料电池内部机理并优化设计,对推动其商业化进程非常重要。”

  据悉,焦魁教授团队在燃料电池设计理论与方法领域建立了高精度仿真模型,并对电池结构进行优化。团队提出一种适用于商用燃料电池的设计方法,建立了大尺寸燃料电池三维加一维仿真模型,其计算效率较传统三维模型提升10—20倍,可以快速提出多种电池设计方案并缩短研发周期。

  该论文的共同通讯作者北京亿华通科技股份有限公司副总经理李飞强博士表示,“以氢燃料电池为例,亿华通使用这种新方法设计的燃料电池,其电化学反应的一致XⅩXⅩ日本性和流阻分配的一致性等指标较目前市场主流产品能够提升20%以上,而厂商设计制造的成本则可降低至目前的60%,研发周期可以缩短至原来的1/3。”

  据了解,焦魁团队提出的数字化辅助设计方法具备通用性,能够应用于任意商用燃料电池,可有效缩减电池研发时间并降低成本,推动其商业化进程。此外,该方法还可拓展至其他诸多电化学装置领域,如锂电池、电解池等。(完)
