PROGRES – PROduction of GRaphene coated platES for fuel cells

Progres项目建立在以前的Innovate UK项目的基础上，将解决重量敏感型无人机(和其他)动力总成应用的超轻量化挑战。它将致力于工业化和高级化生产石墨烯、高导电性和耐腐蚀的聚合物涂层，有可能实现高达90%的成本节约。轻质堆栈使无人机能够飞得更高、更长时间，与现有的电池技术相比，具有更强的系统操作能力。涂覆板约占燃料电池重量的80%，但减轻质量需要创新板堆材料/涂层。同样，轻量化也是进入汽车和便携式市场的关键。作为公认的航空航天材料，Progres还致力于验证钛和铝箔的生产规模工艺。钛代表着燃料电池堆轻量化的(第一步)变化，但需要新的供应链和补充的上游/下游生产和质量控制工艺；以及扩大到大批量/低成本生产的潜力。还将评估使用全屏障保护(高)导电涂料的技术可行性，以利用铝材的卓越重量/性能潜力。总阻隔性将是确保性能不会因表面极低pH(&lt；1)电解液的进入而降级的关键。延长的使用寿命将进行基准测试，降级最小，可接受的运行时间为800小时。一个成功的项目成果将在全球无人机市场上建立以英国为基础的能力。“

"The PROGRES project builds on previous Innovate UK projects and will address super light-weighting challenges for weight sensitive UAVs (and other) powertrain applications. It will aim to industrialise and upscale production graphene enabled, highly conductive and corrosion resistant polymer coatings with the potential to achieve cost savings of up to 90%.Light-weighted stacks enable UAVs to fly higher and longer with enhanced, system operational capabilities over the incumbent battery technology. Coated plates make up ~80% of the weight of a fuel cell, but mass reduction requires innovation of the plate stack materials/coatings. Similarly, light-weighting is key in accessing automotive and portable markets. As generally accepted aerospace materials, PROGRES also aims to validate production scale processes for Ti and Al foils.Ti represents a (first) step change in light-weighting of fuel cell stacks, but requires new supply-chains and complementary upstream/downstream production and QC processes; and the potential to scale to high-volume/low-cost production. The technical feasibility of using total-barrier protection (highly) conductive coatings will also be assessed for Aluminium to harness its superior weight/performance potential. Total-barrier properties will be key to ensuring that performance does not degrade due to the ingress of very low pH (<1) electrolytes at the surface. Extended operational life will be benchmarked, with minimal degradation and acceptable running times \>800hrs. A successful project outcome will establish a UK based competency within a global UAV marketplace."
