基于氢气低温催化燃烧的燃料电池低温启动研究进展
Research progress of fuel cell cold startup based on hydrogen catalytic combustion
摘要
Abstract
When contrasting with traditional power system,fuel cell has a lot of advantages. But it still has many practical problems,such as low-temperature cold startup. Different strategies of fuel cell cold startup were discussed. Some related researches on hydrogen catalytic combustion and fuel cell cold startup were summarized and analyzed and the factors affecting the catalytic combustion were investigated. Hydrogen low-temperature catalytic combustion provided one way to achieve effective and reliable startup of fuel cell. Hydrogen could achieve stable combustion in a micro-tube for different reaction models. Surface catalytic combustion restrained gas phase combustion. The highest temperature could be obtained when surface catalytic combustion and gas phase combustion occurred at the same time. Inlet velocity,conductive wall and its material,tube diameter as well as equivalent ratio of hydrogen/air mixture had significant influence on catalytic combustion of hydrogen.关键词
