Ensuring the purity of titanium and other materials is also crucial , as impurities can affect the performance and longevity of PTLs . Rigorous quality control measures are necessary to maintain high quality standards .
Structural design and fabrication require PTLs to have precisely controlled properties , such as thickness , porosity , pore size distribution , and surface roughness . Achieving these specifications demands advanced manufacturing techniques and meticulous process control . Additionally , the PTLs must provide mechanical support to the CCM , especially under differential pressure conditions . This balance between mechanical strength and flexibility can be difficult to achieve but is essential for the functionality of the PTL .
Coating and surface treatments enhance corrosion resistance and electrical conductivity but present significant challenges . Applying coatings , such as platinum , is a delicate process ; they must be uniform and adhere well to the substrate , requiring precise control over the deposition process . However , due to the cost of platinum group metals ( and other high-performance coatings ), coatings are an expensive process . To reduce the overall cost of PTLs , the exploration of alternative materials and the development of cost-effective coating techniques are well underway .
Scaling production is necessary as the demand for electrolyzers grows . Manufacturers must scale up production while maintaining quality and performance . This involves developing scalable manufacturing processes that can produce PTLs in large quantities without compromising on specifications . Additionally , the electrolyzer industry is rapidly evolving , with continuous improvements in design and performance . PTL manufacturers must quickly adapt their processes to accommodate new designs and specifications .
