HOMEWORK $1$

$$ Ideal solid oxide fuel cell $($SOFC$)$ is operated at $1000K$ temperature. Fuel cells use CO

as the fuel, which is oxidized at anode to $CO2$ using oxygen. The pressure of the anode

is $\frac{5}{b}ar,$ and the cathode is $\frac{10}{b}ar.$ The flow of CO to the anode is $0\mathrm{.}01mo\frac{l}{s}$ at $1000K$

temperature. The oxygen flow temperature is $1000K.$

Calculate for the fuel cell

$$ Fuel cell voltage $(1p)$

$$Electrical power $(1p)$

$$Theoretical fuel cell efficiency $(1$p$)$

$$ Thermal power transferred to surroundings $(1$p$)$
