Coated Aluminium Electrode Plates for Air Cooled (AC) PEMFC Stacks - CAEPAC

CAEPAC将确定用于PEM（质子交换膜）燃料电池的轻质合金衬底涂覆极板的可行性。PEM燃料电池在所有类型的燃料电池中具有最高的功率密度，这使得它们在需要最小尺寸和重量的运输和便携式应用中特别具有吸引力。空气冷却燃料电池显著降低了设备平衡的复杂性，从而减轻了重量（和成本），使Intelligent Energy的AC（空气冷却）技术特别适用于低功率汽车应用，例如轻型车辆的主驱动和增程器驱动。传统的PEM燃料电池使用石墨制成的极板（体积大，加工成本高）或不锈钢制成的极板，特别是用于运输。对于汽车应用，在一个多千瓦的电池组中需要100个电池，因此，如果这些组件可以廉价制造，并且具有相似的性能和寿命，那么每个板相对较小的重量减轻对整个系统来说将是重要的。CAEPAC将开发新型涂层轻质合金板，并研究其在电池和堆叠中的性能，并进行详细的事后分析。

CAEPAC will establish the feasibility of coated electrode plates of lightweight alloy substrates for PEM (ProtonExchange Membrane) fuel cells. PEM fuel cells display the highest power densities of any of the fuel cell types,which makes them particularly attractive for transportation & portable applications where minimum size andweight are required. Air cooled fuel cells significantly reduce balance-of-plant complexity, hence weight (andcost), making Intelligent Energy’s AC (Air Cooled) technology particularly suitable for lower power automotiveapplications such as primary and range extender drives for lightweight vehicles. Conventional PEM fuel cellsutilise electrode plates which are made from graphite (bulky and expensive to machine) or, particularly fortransport, stainless steel. For automotive applications, 100s of cells are needed within a multi-kW stack, hencea relatively small weight saving per plate will be significant for the whole system, provided such componentscan be manufactured cheaply and with similar performance and longevity. CAEPAC will develop novel, coatedlighweight alloy plates, and investigate their performance in cells & stacks, with detailed post-mortem analysis.
