Polymer electrolyte fuel cell (PEFC) vehicles are anticipated to lower well-to-wheel energy consumption, and reduce emissions of green house gases (GHG) and other air pollutants. The current generation of fuel cell vehicles have demonstrated all the performance attributes that customers expect, such as long range, fast re-fuelling and cold start. However, the fuel cells are still physically too large, and too costly to enable successful commercialization of this technology. One of the major contributors to fuel cell costs is the platinum used inside the fuel cell electrodes. In order to reduce the amount of platinum it is necessary to increase the electrical power produced per gram of catalyst (W/gPt) by operating the fuel cells at high current densities (e.g., above 2.5A/cm2). To achieve this goal, the fuel cell electrodes need to be redesigned. Mathematical models are required in order to understand the physical process occurring inside the cell and to

聚合物电解质燃料电池（PEFC）汽车有望降低从油井到车轮的能耗，并减少温室气体（GHG）和其他空气污染物的排放。当前一代燃料电池汽车已经展示了客户期望的所有性能属性，例如长距离，快速加油和冷启动。然而，燃料电池在物理上仍然太大，成本太高，无法实现这项技术的成功商业化。燃料电池成本的主要贡献者之一是燃料电池电极内部使用的铂。为了减少铂的数量，有必要通过在高电流密度（例如，高于2.5A/cm2）下操作燃料电池来增加每克催化剂产生的电能（W/gPt）。为了实现这一目标，燃料电池电极需要重新设计。为了理解细胞内部发生的物理过程并对其进行分析，需要建立数学模型
