Method and system for producing hydrogen, electricity and co-production

摘要

A combined hydrogen and electricity supply system (1) for producing hydrogen (80), electrical Power (P) and co-production, the system comprising a variable electrical load (6) for varying the amount of impedance on the system, a pre-reformer (3) connected to a stream of carbonaceous fuel (20), a stream of steam (40) and connected to a heating source (9), wherein said pre-reformer (3) produces a first reformate gas comprising at least hydrogen, carbon monoxide and unconverted carbonaceous fuel, wherein the pre-reformer (3) is responsive to the amount of heat provided by the heating source, a solid oxide fuel cell stack (2) coupled to the variable electrical load (6) and coupled to the first reformate gas, wherein the ratio between electrical power (P) and amount of hydrogen (80) produced depends at least on the variable electrical load (6) and the heat provided by the heating source (9).
