Problems solved by technology

[0004] However, as such a gasification device is miniaturized, the flow rate becomes smaller, so it is a structure that easily overheats the fuel, etc., so when the fuel is vaporized, the fuel bumps irregularly, and liquid droplets are easily mixed into the gas. It is difficult to control the stable vaporization of the liquid obtained by vaporization
For example, when a substance mixed with various liquids with different boiling points is vaporized, such as fuel and water, the impact of bumping is large, and control becomes more difficult.
[0005] Such unstable factors will destabilize the reforming performance in the reformer or the power generation performance in the fuel cell when the rear reformer and fuel cell are arranged.

Description

technical field [0001] The present invention relates to a gasification device for vaporizing liquid, a fuel cell equipped with the gasification device, and a gasification method. Background technique [0002] In recent years, fuel cells have attracted attention as a clean power source with high energy conversion efficiency, and are widely used in fuel cell vehicles and electrified houses. In addition, the practical application of fuel cell power sources has also been studied in portable electronic devices such as mobile phones and notebook personal computers, where the research and development of miniaturization is rapidly progressing. [0003] Fuel cells are classified into two types: upgrading method and fuel direct method. The reforming method (also referred to as reforming method) is, for example, a method in which hydrogen is generated from fuel and water by a reformer, and then the generated hydrogen is supplied to a fuel cell, such as steam reforming. The fuel direc...
