A fuel cell works like a battery. It consists of two electrodes where the reactions would occur and an electrolyte solution which allows for caharged particles to flow. In a fuel cell that uses hydrogen and oxygen as reactants. The hydrogen would enter the cell at the anode where oxidation would happen. So that the species that is formed in the anode side would be hydronium ions and electrons. The oxygen, on the other hand, would enter the cathode electrode where reduction occurs. The species that are produced in this side of the cell are water molecules. Together, the net reaction is called a redox reaction.

Answer:
The worst option of energy source for the rescue team would be - nuclear, hydroelectric, combustion and fuel burning all are worst option fro max to less worst.
Explanation:
The best option for the energy source for the rescue team would be hand canker, lever as it is mechanical energy generator does not require anything but hand movement to generate energy to charge equipment and easily carry anywhere.
Solar, wind energy are also helpful for rescue team but nuclear energy, hydropower, fuel burning energy source are risky, not handy and costly options.
Thus, the worst option are- nuclear, hydroelectric, combustion and fuel burning energy source.
