本研究針對PEMFC在平面式串聯的堆疊電池組上，提出並測試一種新穎的平面配置模組化(以4顆為一個單位)設計，以微電鑄的方式在單一流道板上設計製作出兩種不同的電極，本研究中以4、8、12、16顆電池串聯的電池組進行測試。該模組塊是以商業化的角度來設計，製作容易且能快速組裝，具有很大發展潛力。
以銅基材的金屬板加上LIGA-like微製程技術，在銅片上面製作出兩種不同的模組塊流道板。以此兩種模組塊流道板再加上質子交換膜(MEA)，組成四種不同電池數量(4、8、12、16顆)的電池組來進行VI/PI的性能測試。
模組化設計以1個模組塊(4顆電池)、2個模組塊(8顆電池)、3個模組塊(12顆電池)和4個模組塊(16顆電池)的性能測試結果來看，在VI/PI性能曲線上有明顯的改善，證明此模組化的設計相較於一般電池組在組裝上更有效率且能減少組裝時的性能減損；並且能根據不同幾何形狀的電池配置需求來進行結構設計。

The newly-designed planar micro fuel cell stack is based on a special pin electrode design incorporating 4 cells, 8 cells, 12 cells and 16 cells. These cells are connected in series on a common supporting plate. In addition, compared to its traditional counterpart, this planar PEM fuel cell stack has improved volume and gravimetric power density. Focusing on the PEMFC planar series cell stack, this study proposes a novel planar modularized design (four cells as a unit).
The microelectromechanical process is adopted to produce two different electrodes on a single flow field plate. Moreover, this study conducts experiments on 4, 8, 12 and 16 cells in series. These cells are designed as modules to be commercialized; therefore, they are easy to manufacture and rapid to assemble, thus demonstrating significant development potential. The LIGA-like microfabrication technique allows for the production of two different modularized flow field plates on metal boards based on copper. To conduct VI/PI performance tests, these two plates can be integrated with MEA to manufacture cell stacks with different amounts of cells (4, 8, 12 and 16).We conduct performance experiments on various sizes of modules: 1 module (4 cells), 2 modules (8 cells), 3 modules (12 cells), and 4 modules (16 cells). The results show that the VI/PI performance curves are significantly improved, verifying that this modularized design is more efficient and can reduce performance loss caused during the assembly process. Furthermore, structural design can be adjusted according to the requirement of cells of various geometric forms.
