What is a major cost limitation of hydrogen fuel cells?

• A. The catalysts, such as platinum, are expensive.
• B. Hydrogen storage is unlimited and free.
• C. There is no need for maintenance or operation costs.
• D. They are cheaper to manufacture than conventional engines.

Answer: (A)

At the heart of the cost challenge with hydrogen fuel cells is the need for catalysts, typically platinum, to speed the electrochemical reactions at the electrodes. Platinum is expensive and scarce, so the cost of the catalyst layer becomes a large and persistent portion of the overall fuel cell stack price. This high material cost, along with the costs tied to durable, high-performance catalysts, drives a major barrier to affordable, large‑scale deployment. The other statements don’t capture the main financial hurdle: storing hydrogen involves its own energy and infrastructure costs, maintenance and operation incur ongoing expenses, and fuel cells aren’t currently cheaper to manufacture than conventional engines when you factor in materials, manufacturing complexity, and system balance-of-plant.
