Abstract

The invention provides an online hydrogen production system and a method. The system comprises a reforming hydrogen production chamber and a combustion chamber, the reforming hydrogen production chamber is provided with a hydrogen filter element, and an air inlet, an unreacted raw material outlet and a hydrogen outlet are formed in the reforming hydrogen production chamber; the reforming hydrogenproduction chamber is disposed in the combustion chamber, and a heating unit is disposed between the combustion chamber. The method comprises the steps of (1) gasifying a reforming hydrogen productionmaterial to obtain a gasification material; (2) simultaneously heating the reforming hydrogen production chamber and the combustion chamber by using the same heat source, using the gasification material as a raw material in the reforming hydrogen production chamber to reform and produce hydrogen so as to obtain a hydrogen-containing mixture, and burning the unreacted gasification material in thecombustion chamber; (3) separating the the hydrogen in the hydrogen-containing mixture to obtain the hydrogen product. The system and method have high hydrogen production rate per unit volume / weight,good stability, fast response, complete fuel reaction, safety, reliability and low cost.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production, and relates to an on-line hydrogen production system and method, in particular to an on-line hydrogen production system and method for fuel cell hydrogen supply. Background technique [0002] Proton exchange membrane fuel cells (PEMFCs) have fast start-up speed, high power density, low environmental pollution, and simple structure. They are considered to be the energy supply technology with the most development potential in the 21st century. Widely used in military, geology, communications, transportation and other fields. with H 2 The technology of PEMFCs as fuel is basically mature, but due to the H 2 Low density, flammable and explosive, storage and transportation difficulties limit its practical application. In recent years, the on-line hydrogen production technology of fuel cells has attracted people's attention. It uses a catalytic reactor to convert portable liquid fuel into...
