氫氣及替代能源技術

要替燃料電池提供最佳夾緊帶解決方案需要滿足哪些要求？

在移動解決方案中，例如在重型貨車、公共汽車、火車和船舶等需要大量能量和高功率水平的應用中，單獨使用電池很快就會在經濟和技術上達到極限。在這種情況下，燃料電池與高壓氫氣罐系統相結合是一種零排放的替代驅動和工作方式。

HYDAC為燃料電池應用和氫氣罐系統提供創新的安裝技術解決方案。除了安裝高壓罐之外，我們還在燃料電池的周圍環境中使用我們的束緊帶解決方案。燃料電池製造商有時使用螺栓來束緊其燃料電池堆。然而，使用這種解決方案無法實現對堆的力的最佳分佈，因為接觸壓力分佈不均勻。這可能導致單個雙極板之間的洩漏，從而導致能量損失並惡化燃料電池系統的效率。在束緊燃料電池堆時，使用束緊帶而不是傳統的螺栓，其技術優勢在於接觸力更均勻地施加在燃料電池的密封上。束緊帶解決方案還可以減輕燃料電池堆的重量，優化安裝尺寸並簡化安裝和維護過程。
What requirements does an optimum clamping band solution for fuel cells need to meet? In mobile solutions where large amounts of energy and high levels of power are required over a prolonged period, for example in heavy goods vehicles, buses, trains and ships, batteries used on their own quickly reach their limits, both economically and technically. In such cases, a fuel cell used in conjunction with high-pressure tank systems for hydrogen is an alternative way to drive and work with zero emissions. HYDAC supplies innovative mounting technology solutions for fuel cell applications and hydrogen tank systems. Alongside mounting high-pressure tanks, we also use our clamping band solutions in the immediate surroundings of the fuel cell. Fuel cell manufacturers sometimes use threaded rods to clamp their fuel cell stacks. It is not, however, possible to achieve an optimum distribution of forces on the stack with this solution as the contact pressure is distributed unevenly. This can result in leakage between individual bipolar plates, leading to energy losses and worsening the system efficiency of the fuel cells. When clamping fuel cell stacks, the technical advantage of using clamping bands rather than conventional threaded rods is that the contact forces are applied to the seals of the fuel cells much more evenly. The clamping band solution also reduces the weight of the fuel cell stack, optimises installation dimensions and simplifies the mounting and maintenance processes.
