| 摘要 |
The present invention relates to a substrate-supported process for continuou s and automated manufacturing of microfibrous fuel cells and other electrochemical devices. Specifically, a removable substrate layer (92) is formed around an inner current collector (82), followed by sequentially coating multiple structure layers, such as the inner catalyst layer (102), t he membrane separator (112), and the outer catalyst layer (122), over such removable substrate layer (92), and subsequent removing such removable layer (92), so as to form a lumen (91) around the inner current collector (82), to allow passage of fluid therethrough. The removable substrate layer (92) preferably comprises a water-soluble polymer, such as polyvinyl pyrrolidone (PVP), polyvinyl alcohol (PVA), or polyethylene glycol (PEG). |
