Description
本發明係有關一種可攜式電力PCB極板，尤指一種材質輕薄強韌、加工性好、成本低且導電度較高的應用在可攜式氫能電堆之可攜式電力PCB之雙極流道板及其製造方法。The invention relates to a portable power PCB plate, in particular to a portable power PCB of a portable hydrogen energy stack, which is light and strong, has good processing property, low cost and high conductivity. Extreme flow channel plate and its manufacturing method.
可攜式氫能電堆中最常用的是石墨碳板或樹脂碳板製成的可攜式電力PCB極板，然而石墨的材料成本高，且加工與製作不易，雖具有良好的導電性，但存在重量比較高、易破裂的缺點，目前雖也有利用金屬板加工後形成的流道，該金屬流道的導電性雖更佳(約為石墨的一百倍)，但同樣存在重量不輕及加工製作不易的問題；也有業者將樹脂、碳粉、奈米碳管及添加劑使用射出成型來製作碳板，雖可以量產並省去加工費，但昂貴的開模費及牽扯的技術問題也令人頭痛。The most commonly used portable hydrogen energy stack is a portable power PCB plate made of graphite carbon plate or resin carbon plate. However, the material cost of graphite is high, and it is difficult to process and manufacture. Although it has good electrical conductivity, However, there are disadvantages of relatively high weight and easy rupture. At present, although the flow path formed by processing the metal plate is used, the conductivity of the metal flow channel is better (about one hundred times that of graphite), but the weight is not light. And the problem of processing is not easy; some companies use resin, carbon powder, carbon nanotubes and additives to produce carbon sheets by injection molding, although mass production and processing costs are saved, but expensive mold opening fees and technical problems involved It is also a headache.
