A 3.5 tonne forklift containing proton exchange membrane fuel cells (PEMFCs) and lithium-ion batteries was manufactured and tested in a real factory. The work efficiency and economic applicability of the PEMFC forklift were compared with that of a lithium-ion battery-powered forklift. The results showed that the back-pressure of air was closely related to the power density of the stack, whose stability could be improved by a reasonable control strategy and membrane electrode assemblies (MEAs) with high consistency. The PEMFC powered forklift displayed 40.6% higher work efficiency than the lithium-ion battery-powered forklift. Its lower use-cost compared to internal engine-powered forklifts, is beneficial to the commercialization of this product.
研制并测试了一款装有质子交换膜燃料电池（PEMFC）和锂离子电池的 3.5 吨叉车，将 PEMFC 叉车与锂离子电池叉车的工作效率和经济适用性进行了对比。结果表明，空气背压与堆的功率密度密切相关，通过合理的控制策略和具有高一致性的膜电极组件（MEA）可以提高其稳定性。与锂离子电池叉车相比，PEMFC 叉车的工作效率高出 40.6%。与内燃机叉车相比，其较低的使用成本有利于该产品的商业化。
