研究目的
To develop a novel dual fuel micro?uidic fuel cell system powered by both methanol and methanol-derived hydrogen via photocatalysis, achieving improved cell performance while eliminating hydrogen transportation, storage, and safety issues.
研究成果
A novel dual fuel MFC system with in-situ hydrogen generation from methanol solution driven by simulated solar light was successfully demonstrated. The system's performance under light on condition increased by more than 10 times for a water/MeOH ratio of 2 or above, recommending this ratio for optimal performance in both dark and light conditions.
研究不足
The study is a proof of concept, indicating that further improvements are needed in photocatalyst efficiency, electrode modification, and reactor design for practical applications.
1：Experimental Design and Method Selection:
The study employs a dual fuel micro?uidic fuel cell system powered by methanol and hydrogen generated via photocatalysis. Pt/P25 is used as the photocatalyst.
2：Sample Selection and Data Sources:
Methanol and water mixtures at different ratios are used as fuel sources. Hydrogen generation rates are measured using an on-line gas chromatograph analyzer.
3：List of Experimental Equipment and Materials:
Includes a 300 W Xenon lamp for simulated solar light, a double layer glass beaker as the photoreactor, and micro?uidic fuel cell components made of PMMA and silicon rubber.
4：Experimental Procedures and Operational Workflow:
The photocatalyst is prepared by UV photodeposition. The MFC performance is tested under both light on and off conditions, with polarization curves measured using an electrochemical work station.
5：Data Analysis Methods:
The hydrogen generation rate is analyzed using gas chromatography. The MFC performance is evaluated based on polarization curves and power density measurements.
