摘要

综述了直接甲醇燃料电池技术在功率密度、效率和综合系统运行等方面的研究现状。提高功率密度的关键挑战是与低空气流速下的运行相结合，以保持水平衡，并实现有吸引力的系统质量和尺寸。改进的催化剂和低甲醇渗透性的膜是实现这些改进的关键。讨论了用于电池更换的微型DMFC所面临的挑战。降低催化剂和膜成本的可能性表明，优质功率应用(100 W-5 kW)可能是DMFC进入商业市场的早期起点。

Direct methanol fuel cells-status, challenges and prospects

The status of direct methanol fuel cell technology with respect to power density, efficiency and integrated system operation have been summarized. The key challenge in improving power density is combining with operation at low air flow rates in order to maintain a water balance, and achieve attractive system mass and size. Improved catalysts and membranes with low methanol permeability are key to achieving these improvements. Challenges relating to miniature DMFC for battery replacement are discussed. Possibilities of reduction in catalyst and membrane cost suggest that premium power applications (100 W-5 kW) could be an early point of entry for DMFC into commercial markets.
