Hydrogen generators and integrated hydrogen generator/fuel cells systems are operated by determining the condition of the hydrogen generator and the condition of the fuel to the hydrogen generator for selection of predetermined flow rates for each of the externally-provided raw materials. The processes of the invention can provide rapid transitions between hydrogen production rates while enabling enhanced efficiency and stability during transient operations.

Feedforward control processes for variable output hydrogen generators

A process, control system and apparatus for controlling the air side flows to the major components of a fuel processor apparatus are provided. The control system employs a multi-capacity blower provides process air to a partial oxidation reactor and a preferential oxidation reactor. The multi-capacity blower preferably provides a portion of the process air through a control valve to the partial oxidation reactor and the remaining portion of the process air is passed through a flow restrictor to supply process air to the preferential oxidation reactor. The control system of the present invention is simple, low cost and reliable.

Process, control system and apparatus for the distribution of air in a fuel cell/fuel processor system

This invention relates to a compact apparatus for generating hydrogen. More particularly, this invention relates to a compact hydrogen generating apparatus suitable for use in conjunction with a fuel cell. The compact hydrogen generating apparatus comprises a fuel processor reactor having an integrated pre-reforming zone embedded within a secondary reforming zone.

Fuel processor reactor with integrated pre-reforming zone

A novel integrated system for the co-production of heat and electricity for residences or commercial buildings is based on the cracking of hydrocarbons to generate hydrogen for a fuel cell. Compared to prior art reforming methods for hydrogen production, the cracking reaction provides an input stream to the fuel cell that is essentially free of CO, a known poison to the anode catalyst in many fuel cell designs, such as PEM fuel cells. The cracking reaction is coupled with an air or steam regeneration cycle to reactivate that cracking catalyst for further use. This regeneration can provide a valuable source of heat or furnace fuel to the system. A novel control method for system adjusts the durations of the cracking and regeneration cycles to optimize the recovery of reaction heat.
