G Assume that you are designing a reformer reactor that is part of a fuel cell fuel processor system that will use natural gas (primarily methane, CH4) as the primary fuel for a 100 kWe fuel cell. (a) Write balanced chemical expressions for the steam reformation, partial oxidation, and water-gas shift reactions that could occur for the various design options of your reformer reactor. (b) Determine the flow-rate of methane required in kg/hr (note that you must make some assumptions about efficiency or voltage to determine the flow required). (c) Determine the desired steam flow-rate in kg/hr for a steam reformer and note your assumptions/reasons for selecting this flow-rate. (d) Determine the desired air flow-rate in kg/hr for a partial oxidation reformer design. Must add only enough air to produce 0.5 moles O2 per mole of CH4. (e) Which reformer design do you prefer and why
