Abstract:
1. A manufacturing method of fuel cell having micro sensors and polymer layers, comprising: [1] preparing a first film-electrode made by a silicon-based material, said first film-electrode having a working surface, depositing a first polymer layer on said working surface; [2] coating a first photo-resist layer on said first polymer layer by utilizing lithographic processing technology, said first photo-resist layer having a first pattern to define on said first polymer layer a first exposed portion and a first blocking portion; [3] depositing a chromium layer on said first photo-resist layer and said first exposed portion of said first polymer layer to a predetermined thickness; [4] depositing a gold layer on said chromium layer; [5] removing from said first blocking portion of the first polymer layer said first photo-resist layer, said chromium layer, and said gold layer thereon; [6] depositing a second polymer layer on said first blocking portion of the first polymer layer layer and said gold layer; [7] coating a second photo-resist layer on said second polymer layer by utilizing lithographic processing technology, said second photo-resist layer having a second pattern to define on said second polymer layer a second exposed portion and a second blocking portion; [8] conducting a plasma etching on said second exposed portion of said second polymer for etching downward, and forming a plurality of metal connecting portions connecting with said gold layer; [9] removing said second photo-resist layer; and [10] disposing lead lines to connect with said metal connecting portions, assembling a second film-electrode, and assembling a pair of bipolar plates, wherein said first film-electrode and said second film-electrode are sandwiched by said bipolar plates, wherein a fuel cell having micro sensors and polymer layers is formed.
