State experimental solid-oxide fuel cells that use butane

Reference no: EM13176594

Experimental solid-oxide fuel cells that use butane (C4H10) as the fuel have been reported recently. These cells contain composite metal/metal oxide electrodes and a solid metal oxide electrolyte. Consider the following unbalanced half-reactions:

C4H10(g) + O-2(s) %u2192 CO2(g) + H2O(l) + e- O2(g) + e- %u2192 O-2(s)

What is a fuel-cell? What was the first example of a fuel-cell?

Balance this REDOX reaction under acidic conditions. Identify the oxidizing agent and reducing agent.

How many liters of butane are required to produce a constant current of 10.5 A for 8.00 hr at 20 oC and 815 mm Hg?
