(a)
To determine: The difference between a battery and fuel cell.
(a)
Answer to Problem 1DE
Solution: The major difference between a battery and fuel cells is that batteries are the self-contained system that does not require the continuous supply of reactants, while fuel cells require continuous supply of reagents.
Explanation of Solution
A battery is a portable source of energy that contains one or more voltaic cells. They are self-contained system that does not require the continuous supply of reactants.
Fuel cells are generally voltaic cell that convert chemical energy into electrical using conventional fuels such as
The major difference between a battery and fuel cells is that batteries are the self-contained system that does not require the continuous supply of reactants, while fuel cells require continuous supply of reagents.
(b)
To determine: If the fuel used in a fuel cell can be solid.
(b)
Answer to Problem 1DE
Solution: Yes, fuel used in a fuel cell can be solid.
Explanation of Solution
Solid fuels can also be used in fuel cell such as a hard ceramic compound of metals like calcium and zirconium oxide is used as electrolytes in fuel cells.
Yes, fuel used in a fuel cell can be solid. For example, hard ceramic compound of metals like calcium and zirconium oxide is used in fuel cells.

If they are brought together to x = x, the potential energy is related to the total force P by dU dx = P Given this, qualitatively sketch the variation of U with x. What happens at x=x? What is the significance of x = x, in terms of the potential energy? 0 P, Force 19 Attraction Total Repulsion x, Distance Figure 2. Variation with distance of the attractive, repulsive, and total forces between atoms. The slope dP/dx at the equilibrium spacing xe is proportional to the elastic modulus E; the stress σb, corresponding to the peak in total force, is the theoretical cohesive strength.arrow_forward
