由於傳統親水電極作法是將觸媒噴塗在平整碳層上面，觸媒利用率只在與氣體和觸媒兩者之間的接觸面上反應，靠近質子交換膜內部觸媒就無法完全反應到，為了增加更多觸媒的反應，於是在碳層上製作疏水柱狀結構，此疏水柱狀結構內部建立氣體通道比平面碳層結構中氣體通道更容易延伸至更靠近膜內部的觸媒，使得觸媒與氣體接觸的表面積更多，所以也就能夠提供更多氣體與觸媒相互反應。
由於傳統疏水柱狀結構作法是將碳粉直接噴灑於沉積室後，碳粉經自身重力沉積通過金屬網罩形成疏水柱狀結構，製作上耗時；所以本實驗設計採用電鑄方法製作微孔結構，此結構可以壓印疏水碳層，方便製作疏水柱狀微結構，所以使用微結構金屬片模具製作疏水柱狀結構快速，能縮短製程時間。
實驗首先用微結構金屬片模具壓印陰極側電極之小型與大型疏水柱狀結構，壓印疏水柱狀結構壓力為500kg/cm2；在相同的觸媒量下，小型疏水柱狀表面積增加約為63﹪，性能提升約為55﹪；大型疏水柱狀表面積增加約為30﹪，性能提升約為30﹪；再進一步控制陰極觸媒量，由原本的0.5mg/cm2減半至0.25 mg/cm2，性能也無明顯降低，所以在陰極電極製作疏水柱狀結構達到最佳性能及觸媒利用率後，進一步製作疏水柱狀結構於陽極，觸媒量分別由0.4 mg/cm2減半至0.2 mg/cm2，性能也無明顯降低。
所以由上述說明了觸媒的反應只在與氣體之間的接觸面上，無論導入小型或大型疏水柱狀結構或是觸媒量減半，都可以提升燃料電池之性能表現及節省觸媒使用率。且由兩種不同尺寸大小微結構金屬片模具製作小型或大型疏水柱狀結構，電極功率密度皆可達到720mW/cm2和595mW/cm2。

Abstract
The conventional hydrophilic electrode used to spray the catalyst on the level-off carbon layer and the utilization of catalysts can only be reacted between the gas and the catalyst; however, the internal catalyst of the proton exchange membrane cannot be reacted. In order to increase the reaction of the catalyst, the hydrophobic pillared micro structures (HPMS) are made on the carbon layer, so that the gas can reach the catalyst in the internal membrane so that a reaction on large surface between the gas and the catalyst can be achieved. It is easier to build the gas channel in the internal HPMS than the structures of the carbon layer. As a result, more gas can be sent to the internal catalyst thus enlarging the reaction zone and more reactions between the gas and the catalyst is then achieved.
The carbon powder is sprayed in the conventional HPMS in the deposition process. The HPMS are formed after the gravity process while the powder is passing the metal netmask and the manufacturing time is long. The experimental design uses electroforming to make the micro porous structure so that the hydrophobic carbon layer can be stamped thereby forming the HPMS. It has been proven that the time for the manufacturing process can be shortened if the micro structured metal template is applied.
The micro structured metal template is used to stamp the small and large HPMS on the side electrode of the cathode, the stamping HPMS pressure was 500kg/cm2. With the same catalyst quantity the surface of the small HPMS was raised 63% and its performance was up to 55%; the surface of the large HPMS was raised 30% and its performance was up to 30%. The catalyst quantity of the cathode was reduced from 0.5mg/cm2 to 0.25 mg/cm2 and its performance remains the same.
The experiment’s results indicate that the reaction of the catalyst was only on the surface between the gas and the catalyst. Either small or large HPMS or after reducing the catalyst quantity can all raise the performance of the fuel cell as well as economize the catalyst. And by two kind of different size dimension microstructure metal template manufacture small or large HPMS, the electrode power density all may achieve 720mW/cm2 and 595mW/cm2.
