- Abstract
- In this study, unlike previous study, we fabricated a fabric - based fuel cell with improved flexibility and durability. Eco flex, which is harmless to human, was used to make a flow path. In the fuel, Potassium formate is used for its less burdensome to enviromental pollution. An alkaline electrolyte had on oxidation reaction well with fuel, and instead of acid or hydrogen peroxide, potassium hydroxide is used to prevent corrosion and performance degradation of electrodes. Palladium on carbon was used in anode to oxidize formate, and manganese dioxide was used in cathode to reduce oxygen. In the Y-type tapered electrode, the gap between the electrodes and the shape of the electrode in the flow path were changed. The shape was changed with the aim of increasing the diffusion area by applying a taper to the electrode. When the gap between the electrodes was 1.0mm , maximum current density of 26.233±2.680 (mA/cm2) is gained and maximum power density of 7.686±1.098 (mW/cm2) is achieved. Also, the change in electrode shape located in the flow path was 0.4mm, maximum current density of 22.392±2.184 (mA/cm2) is gained and maximum power density of 7.091±0.865 (mW/cm2) is achieved.
