2. Development of wearable micro fuel cell foundation technique
A. Catalysts
(1) Fuel cell catalysts
○ Fabrication of the Pt-Ni alloy catalyst using graphene supporter
○ Platinum loading minimization and ORR activation increased
○ The ORR activity of the graphene supported Pt-Ni alloy catalyst was highest in the 0.5 molar sulfuric acid solution
○ The ORR reaction of this catalyst follows 4 electron transport pathway and confirms that it has high methanol resistance

(2) Hydrogen evolution catalysts
○ Successful synthesis of NiFeS complex catalyst supported on Nickel foam through simple electrical vapor deposition
○ Due to the Composite effect, the composite catalyst exhibits oxygen generation (231mV) and hydrogen evolution (180mV)
○ This results are comparable to the commercial catalyst (Pt/C 40%)

B. Hydrogen evolution devices
○ Hydrogen evolution experiments were carried out with 1 and 2g of NaBH4 and Ru/C catalysts combination. As a result, the fuel cell can be used for 35min when the flow rate of hydrogen is adjusted to 0.2 SCCM.
○ In case of 5 to 1g mixing ration, the fuel cell can be used for 2h 37min.
○ Confirm that the yield can be improved by adjusting the temperature and pressure of the sealed bottle.

C. Electrolyte membrane
○ Successful synthesis of sulfonated block copolymer and development of electrolyte membrane through solvent casting
○ Development of composite membrane using synthesized block copolymer coupled with graphene oxide hybrid with phosphotungstic acid
○ It shows 3.5 times higher fuel cell performance than commercial electrolyte membrane under low relative humidity condition

D. Fuel cell stack
○ In case of the forced air inflow metal plate fuel cell stack, it shows OCV (4.8V), maximum current density (483mV), and maximum power(20W) for 5 cell stack.
○ The air is forced through the pen. So, the temperature of the fuel cell stack is kept constant at 26 ℃.
○ In the case of the natural convection type fuel cell stack, a separate electrical BOP (Balance of Plant) is installed for optimization of fuel cell performance.
○ Finally, the natural convection type fuel cell stack can be used in flash through the USB terminal part after about 3 minutes through the fuel valve and the capacitor of the e-BOP.
○ The load output power consumption is 417mW in the flash ON state.
