Title
(EN) Bonding electrochemical cell components
(ZH) 电化学电池部件的连接
Abstract
(EN)
The invention provides a method for preparing subassemblies for an electrochemical cell or a stack of electrochemical cells, particularly a stack of fuel cells for the direct generation of electricity. The method includes bonding together two or more electrochemical cell components, such as plates, frames, flow fields, shims, gaskets, membranes and the like, to form subassemblies used to make an electrochemical cell stack. The bonding can be accomplished using either polymeric bonds (i.e., adhesives) where polymer and/or metal components are involved or metallurgical bonds (i.e., solder) where metal components are involved. The bonding provides tightly sealed cells and lower electronic contact resistances between components.

本发明提供了一种为电化学电池或电化学电池组,特别是用来直接产生电的燃料电池组制作子组件的方法。该方法包括将两个或多个电化学电池部件,如板、框架、流场、垫片、密封垫、隔膜等连接在一起,形成用于制造电化学电池组的子组件。此连接可使用聚合物连接件(如粘结剂)使用金属连接件(如焊料)实现,前者涉及聚合物和/或金属部件,后者涉及金属部件。该连接提供密封的电池,而且部件间的接触电阻较低。
