Fuel cells are devices that transform chemical energy directly into electrical energy via electrochemical processes, operating continuously with a fuel supply.
1. What is the primary cause that enables a fuel cell to produce electricity continuously?
2. Who is credited with the foundational understanding of the key electrochemical reactions involving hydrogen splitting at the anode and oxygen reduction at the cathode in fuel cells?
3. Which of the following best describes the sequence of steps in fuel cell operation that leads to electricity generation?
Fuel cell — definition?
Device converting chemical to electrical energy electrochemically.
Key reaction — process?
Hydrogen splits; electrons flow; water forms.
Operation steps — sequence?
Hydrogen splits; electrons flow externally; water produced.
Advantages — benefits?
High efficiency, low pollution, no moving parts.
Disadvantages — challenges?
High cost, hydrogen storage, expensive catalysts.
Electrochemical reaction — where?
At electrodes: hydrogen at anode, oxygen at cathode.
