... (e.g., hydrogen) into electrical energy and have the advantages of high efficiency and low pollution ( 1 ). Also, fuel cells can be used widely; from mobile power units to huge power plants. To facilitate fuel cell commercialization, hydrogen production technology needs to be developed ( 2 ). Currently...

... but an increase in limiting current density from a higher hydrogen production. The numerical results show that the flow rates and reformer length are critical design parameters because if not properly designed they can lead to incomplete conversion of the methane fuel to hydrogen in the reformer, which has...

...S. Cordiner; G. de Simone A comprehensive computational model for the design of methane catalytic partial oxidation monolith reactors for hydrogen production has been developed and tested with respect to available experimental data. Allowing a simplified description of the heat release mechanism...

... of the catalyst on methanol conversion, selectivity, and product yields was evaluated. The addition of zinc enhanced the methanol conversion and hydrogen production. The excess steam promoted the methanol conversion and suppressed the carbon monoxide formation. Different strategies have been mentioned to minimize...
