Peptide bonds are amide connections between two amino acids' -carboxyl and -amino groups.
The covalent link created by the dehydration reaction (loss of a water molecule) between the carboxyl group of one amino acid and the amino group on the next is known as a peptide bond. Peptide bonds are created in polypeptides through a condensation reaction between the carboxyl groups of one amino acid and the amino groups of the following amino acid, all while removing water. When the carboxyl group of one molecule combines with the amino group of the other molecule, releasing a molecule of H2O as a result, a peptide bond is created between the two molecules.

Here we have to choose the challenge which is faced by the scientist to make a hydrogen fuel cell by using water.
The challenge that the scientists are facing a. decomposition of water requires a high energy.
For the generation of fuel cells by hydrogen the use of water (H₂O) is a challenging task as the H-O bond in water is so strong and need high activation energy.
As per the mechanism of hydrogen fuel cell generation of H₂ is compulsory. Water remains in its solution as H₂O⇔H⁺ + OH⁻. The breaking of hydroxide ion (OH⁻) to form free hydrogen need a high energy, which cannot meet easily by any energy source.
The sun is always a renewable energy source as the energy of sun is infinitive.
The decomposition of water will only produce oxygen (O₂) and hydrogen (H₂) among which H₂ will be used in the fuel cell and O₂ is not at all harmful.
The excess O₂ is always good for the environment as it is the breathing source in the living system.
