燃料電池用雙極板的密封

在 ViscoTec 技術中心進行工藝優化點膠測試
當前，全球對環境兼容和高效移動的需求使燃料電池技術重新回到戰略討論的前沿。
同時，燃料電池和氫氣前景廣闊。從市場和技術成熟度來看，燃料電池應用的市場份額仍然很小，但已經獲得了很大的發展勢頭。根據這一發展，最近在 ViscoTec 技術中心進行了點膠測試，使用 Wacker 有機硅密封燃料電池的雙極板。

點膠測試的目的：
按照關于高度公差的精確規范將密封接縫應用于雙極板上。通過此類測試，可以確定工藝參數并將風險降至最低——以便能夠從中推斷出持續改進措施。使用 2-component Dispenser P4/4 以 0.12 ml/s 的分配速度進行測試。沒有超過密封膠珠的公差。密封珠的公差為 +/- 0.05 毫米——這已經是一個令人印象深刻的結果，點膠技術專家希望進一步改進。

系統設計適應客戶的需求或相應應用的要求。例如，可以單獨調整分配容量。作為工藝安全、精確和可擴展的點膠技術的系統供應商，ViscoTec 是各行各業廣受歡迎的合作伙伴。在特殊業務開發部門的幫助下，ViscoTec 與研究機構、機器制造商和最終客戶合作改進和自動化生產方法。ViscoTec 可以在這里發揮廣泛的協同作用，但由于擁有自己的技術中心，它還可以進行廣泛的試驗并產生工藝知識。
在燃料電池領域，點膠專家也在支持市場的發展，希望讓客戶實現持續增長。行業專家認為，在這個未來的大眾市場中，歐洲的銷售額有望達到 650 億歐元，而全球市場的銷售額有望達到 650 億歐元。1特別是中國、日本和韓國，還有美國，應被視為銷售市場，以便繼續保持國內公司目前的出口實力。為了挖掘氫能和燃料電池行業未來的增長潛力并在國際舞臺上保持競爭力，在未來兩到五年內，通過投資繼續建立和擴大現有能力至關重要。
ViscoTec 隨時準備提供主動支持并創造附加值。畢竟，如果目標是用于粘合或密封元件（例如雙極板）的點膠，那么即使是小批量，也必須能夠實現經濟效益和技術準確性。因此，以適度的投資成本促進訪問至關重要，而且通過深思熟慮的系統配置來確保可擴展性。特別是可擴展性和相關的成本遞減必須為客戶計算。
Sealing of bipolar plates for fuel cells

Dispensing tests for process optimization in the ViscoTec technical center
The current, worldwide demand for environmentally compatible and efficient mobility brings fuel cell technology back to the forefront of strategic discussions.
At the same time, fuel cells and hydrogen promise large potential. Looking at the market and the maturity of the technology, it can be seen, that fuel cell applications still claim a small market share but have already gained a great deal of momentum. In line with this development, dispensing tests were recently carried out at the ViscoTec technical center using a Wacker silicone to seal bipolar plates for fuel cells.
The aim of the dispensing tests: To apply the sealing seam to a bipolar plate in compliance with precise specifications regarding height tolerance. Due to such tests, it is possible to determine process parameters and minimize risks – in order to be able to deduce continuous improvement measures from them. The test was carried out with the 2-component Dispenser P4/4, at a dispensing speed of 0.12 ml/s. The tolerance of the sealant bead was not exceeded. The tolerance of the sealing bead was +/- 0.05 mm – already an impressive result, which the dispensing technology experts want to improve even further.

The system design is adapted to the needs of the customer or to the requirements of the respective application. For example, the dispensing capacity can be adjusted individually. As a system supplier for process-safe, precise, and scalable dispensing technology, ViscoTec is a sought-after partner in a wide range of industries. With the help of special business development units, ViscoTec works together with research institutions, machine builders and end customers on improved and automated production methods. ViscoTec can draw on a wide range of synergies here, but thanks to its own technical center it can also carry out extensive trials and generate process knowledge.
In the fuel cell sector too, the dispensing experts are supporting the development of the market and want to enable customers to achieve continuous growth. Industry experts see a potential of EUR 65 billion in sales in Europe and a further EUR 65 billion in global markets in this future mass market.1?China, Japan, and South Korea in particular, but also the USA, should be considered as sales markets so that the current export strength continues to be maintained for domestic companies. In order to exploit the future growth potential of the hydrogen and fuel cell industry and to remain competitive in the international arena, it will be crucial in the next two to five years to continue to build up and expand existing competencies through investment.
ViscoTec is always ready to provide proactive support and create added value. After all, if dispensing for bonding or sealing components such as bipolar plates is the goal, economic benefits and technical accuracy must be possible even for small quantities. It is therefore crucial to facilitate access with moderate investment costs, but also to ensure scalability by means of a well-thought-out system configuration. Particularly scalability and the associated cost degression must be calculable for customers.
