極板材料導電性及耐蝕性性質為影響生物-電-芬頓燃料電池(Electric Fenton Microbial Fuel Cell, EMFC)之重要關鍵，低碳鋼(Steel Plate Heat Commercial, SPHC)具良好導電性及低成本，惟其耐蝕性較差；本研究藉由電鍍技術鍍上具高防蝕效果之鉻元素及進行材料表面成長奈米碳管(CNT)處理，冀能提升EMFC系統陽極之電性及耐蝕性。實驗包括電化學極化特性、功率密度量測，腐蝕特性塔弗曲線量測，極板親水性測試及金相剖面分析。顯示，SPHC經表面處理後，腐蝕電位從-520 mV提升至-374 mV，腐蝕電流從2.15×10-4 A降低至1.20×10-5 A；在系統電性部分，最大功率密度從35 mW/m2上升至510 mW/m2，提升14.5倍，電流密度從1,155 mA/m2提升至2,455 mA/m2。初步顯示，SPHC經表面鍍鉻及成長CNT將有助於提升極板耐蝕能力及生物-電-芬頓燃料電池性能。

The electrode with conductivity and corrosion resistance is the key to the Electric Fenton Microbial Fuel Cell (EMFC). SPHC have good conductivity and low cost but have poor corrosion resistance. In this research, chromium coating which have high anticorrosive made by electroplate technology and Carbon nanotubes were grown on the coating surface to improve power and corrosion resistance in the EMFC. Experiments include electrochemical polarization characteristics, power density, Tafel corrosion measurement, contact angle measurements and cross-sectional analysis. The results showed that the corrosion potential for SPHC with modification enhanced from -520 mV to -374 mV, the corrosion current reduced from 2.15 × 10-4 A to 1.20 × 10-5 A. In the electrical property measurement, the maximum power density for SPHC with modification raised from 35 mW/m2 to 510 mW/m2, which increased 14.5 times than SPHC without modification. The current density was from 1,155 mA / m2 up to 2,455 mA/m2. The initial results showed that the chrome and carbon nanotubes surface treatments can help improving corrosion resistance of the plate and EMFC performance.
