16.18—Fuel cells use the energy released on the reaction of a fuel with oxygen to generate a voltage Knowledge that methanol

Understand that fuel cells use the energy released on the reaction of a fuel with oxygen to generate a voltage Knowledge that methanol and other hydrogen-rich fuels are used in fuel cells is expected.

Use —fuel cells use the energy released on the reaction of a fuel with oxygen to generate a voltage knowledge that methanol to connect the rule to the data and decision in the question.

This matters because —fuel cells use the energy released on the reaction of a fuel with oxygen to generate a voltage knowledge that methanol determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —fuel cells use the energy released on the reaction of a fuel with oxygen to generate a voltage knowledge that methanol to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Fuel cells use the energy released on the reaction of a fuel with oxygen to generate a voltage Knowledge that methanol is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
