目前，德特威勒已經(jīng)將業(yè)務(wù)能力范圍擴(kuò)大到了氫燃料電池技術(shù)的應(yīng)用領(lǐng)域，助力客戶向氫燃料電池技術(shù)轉(zhuǎn)型。德特威勒與全球領(lǐng)先的燃料電池生產(chǎn)商合作，進(jìn)一步完善了自身高性能系統(tǒng)關(guān)鍵密封件的產(chǎn)品組合及相關(guān)生產(chǎn)技術(shù)，以提供能夠覆蓋燃料電池整條產(chǎn)業(yè)鏈的密封解決方案 。

Datwyler has expanded its capabilities to support customers transitioning to hydrogen fuel cell technology. Working in partnership with leading global fuel cell producers, the company has further strengthened its portfolio of high performance and system-critical sealing materials and associated production techniques to provide solutions that cover the entire value chain - from hydrogen production via electrolyzer technology to actual use in the vehicle – specifically fuel cell.

quot;德特威勒對雙極板 密封件尤其關(guān)注，因為它們是燃料電池中將氫氣(氧氣)分子的化學(xué)能轉(zhuǎn)化成電能的關(guān)鍵部件 quot;，德特威勒材料開發(fā)經(jīng)理 Sarah-Elisabeth Dechent 博士說。quot;BPP 的生產(chǎn)主要有三種基礎(chǔ)材料選擇:金屬、石墨和復(fù)合材料。通過結(jié)合彈性體技術(shù)進(jìn)行的深入測試和分析，我們已經(jīng)確定:在車用燃料電池應(yīng)用中，復(fù)合材料制成的雙極板能實現(xiàn)性能與各種現(xiàn)實因素之間的最佳平衡。與金屬和石墨替代品相比，復(fù)合材料制成的 BPP 重量輕、性價比高、易于加工，并具有出色的耐化學(xué)性。

Datwyler’s focus on seals for bipolar plates are critical, as they are the components within a fuel cell used to produce electricity through harvesting energy previously stored in hydrogen (and oxygen) molecules. The BPPs are produced using three main base material options – metal, graphite and composites. As a result of in-depth testing and analysis in conjunction with our elastomer technologies, we have determined that composite materials will, in mobility applications, achieve the best possible results when weighing challenges against performance. Composite BPPs are light, cost effective, easy to process and provide superior chemical resistance when compared with metal and graphite alternatives.

在燃料電池內(nèi)部，BPP 必須有效密封，并且材料必須能夠承受各種環(huán)境條件，包括與三種獨立介質(zhì) 的長時間接觸。德特威勒的技術(shù)與創(chuàng)新實驗室與歐洲各地的專業(yè)實驗室聯(lián)合測試材料的有效性，且重點關(guān)注離子污染等因素，以確保密封材料能實現(xiàn)最高水平的性能。

Within the fuel cell itself, the BPP must be sealed effectively, and the material must be capable of withstanding a variety of conditions, including prolonged contact with three separate media – hydrogen, humidified air and cooling liquid. Datwyler’s Technology amp; Innovation Labs, combined with specialist laboratories across Europe, are testing the effectiveness of materials, focusing on elements such as ion contamination, amongst others, to ensure the highest levels of performance.

一般來說，彈性體能夠滿足廣泛的密封關(guān)鍵參數(shù)要求，這點已經(jīng)得到充分證實。從對機(jī)械能的高吸收性到出色的耐化學(xué)性，彈性體材料都具備優(yōu)勢。通過與復(fù)合材料 制成的BPP 應(yīng)用相結(jié)合，彈性體在燃料電池技術(shù)應(yīng)用中具有巨大的潛力。

Elastomers, in general, have been conclusively proven to deliver against a broad range of critical parameters. From their high absorption of mechanical energy to their excellent chemical resistance, they have enormous potential for fuel cell technology applications in combination with composite BPP.

quot;德特威勒與領(lǐng)先的 BPP生產(chǎn)商HYCCO合作，聯(lián)合開發(fā)了一種高效的、且可以隨著需求增加進(jìn)行規(guī)模化制造的密封解決方案quot;，Dechent博士總結(jié)道。quot;目前我們正在開發(fā)多種材料選項，隨后將進(jìn)行加工試驗。我們迄今為止已取得的成果證明，在新興技術(shù)領(lǐng)域采用聯(lián)合開發(fā)的方法是取得項目快速進(jìn)展的最佳工作方式。德特威勒在材料專業(yè)知識、卓越運營和解決方案設(shè)計方面具備核心競爭力，憑借全球網(wǎng)絡(luò)的支持，我們可以確保向燃料電池生產(chǎn)商提供可靠且優(yōu)質(zhì)的雙極板產(chǎn)品。

“Datwyler partners with HYCCO, a leading producer of BPP, to co-engineer a sealing solution that is highly effective and also scalable as demand increases,” says Dr. Sarah-Elisabeth Dechent, Manager Material Development at Datwyler. “We are now in the process of developing the material options which will progress to processing trials. The results we have achieved so far prove that a co-engineering approach to emerging technologies is the best way of working. At Datwyler we have the capabilities in material expertise, operational excellence and solution design to ensure fuel cell producers that we can deliver reliability and quality, supported by a global network.”

HYCCO首席執(zhí)行官Romain Di Costanzo表示:quot;我們非常高興HYCCO 與德特威勒成為了戰(zhàn)略合作伙伴，我們將共同開發(fā)并生產(chǎn)具有高性價比的應(yīng)用于質(zhì)子交換膜MEA和雙極板BPP之間的密封墊。德特威勒在彈性體配方和復(fù)雜密封件的批量生產(chǎn)方面擁有豐富的經(jīng)驗。同時，德特威勒已經(jīng)在一流的研發(fā)設(shè)備和能力方面做了大量投資來應(yīng)對未來的各種挑戰(zhàn)。所以，我們對此非常高興并相信，這一強(qiáng)強(qiáng)合作關(guān)系將使HYCCO能夠為重型商用車市場的氫燃料電池提供集成密封功能的復(fù)合材料雙極板的一站式解決方案quot;。

“HYCCO is very pleased about the new strategic partnership with Datwyler. Together we want to develop a cost-effective solution for the production of gaskets for proton exchange membrane BPP. Datwyler has a tremendous experience in elastomer formulation, and mass production of complex sealing parts. Datwyler has invested into best-in-class Ramp;D means to meet the various challenges ahead. We are therefore very pleased and confident that this strong partnership will enable HYCCO to provide a turnkey solution of sealed and assembled composite bipolar plate, for hydrogen fuel cells destined for heavy mobility markets,” comments Romain Di Costanzo, Chief Executive Officer at HYCCO.
