Problems solved by technology

[0005] 1. The hydrogen produced in the accompanying hydrogen production device is a hydrogen-rich mixed gas. The engine fuel system using the mixed gas will expose the weakness of insufficient power when the locomotive needs to run at a high load, because the non-combustible components in the hydrogen-rich mixed gas are diluted If the calorific value of the fuel gas is exceeded, when the locomotive is in a high-load operating condition, it will show the phenomenon that the fuel calorific value is insufficient and the engine power will drop; at the same time, the hydrogen-rich mixed gas is not suitable for most fuel cells.
[0006] 2. In order to improve the power performance of the fuel system of the accompanying hydrogen production engine or when it is applied to the fuel cell, hydrogen must be separated and purified from the hydrogen-rich gas, so it is necessary to add a special separation and purification of hydrogen to the fuel system of the engine or fuel cell device, increasing the complexity of the system structure
[0007] 3. When applied to hydrocarbon fuels, a special desulfurization device must be added to the engine or fuel cell fuel system. When adding a desulfurization device, the complexity of the system will also be increased and more moving space will be occupied

Abstract

The invention discloses a compact traveling hydrogen production device, which is integrated with a tubular separation membrane (m) or a desulfurization cavity (005), or simultaneously integrated with the tubular separation membrane (m) and the desulfurization cavity (005). The device greatly simplifies the structure of a traveling hydrogen production system and saves the limited space of a mobile vehicle, thus leading the practicality of a traveling hydrogen production technology in an explosive motor, a turbine engine locomotive and a fuel cell engine or in mobile power generation to become possible.

Description

Technical field [0001] The invention relates to a portable hydrogen production device applied to power machinery, especially a compact portable hydrogen production device applied to locomotive internal combustion engines and gas turbine engines, fuel cell engines or fuel cell mobile power generation equipment. Background technique [0002] The hydrogen engine has the outstanding advantages of high energy conversion efficiency, good power performance and very little pollution. Hydrogen energy will become one of the ideal clean energy sources, and has attracted great attention and been widely used. However, the biggest obstacle to the widespread use of hydrogen energy lies in the difficulty of its storage and distribution. Its traditional industrial preparation method cannot avoid this difficulty. [0003] Using liquid low-carbon alcohol (or hydrocarbon) fuel as the hydrogen carrier, using engine exhaust waste heat, it is converted into Hydrogen-based hydrogen-rich mixed ga...
