Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that most of the cost of a fuel cell is due to the platinum content?

Yes. Multiple studies substantiate the claim that platinum content constitutes a major portion of fuel cell costs, driving extensive research into platinum-group metal-free or ultralow-platinum catalysts for commercial viability.

Verdict: SUPPORTED · 5 sources for, 0 against · Last checked

The analysis

The retrieved literature consistently supports the premise that platinum and platinum-group metals are major cost drivers in fuel cell technology, prompting widespread efforts to reduce platinum loadings or find alternative catalysts to lower overall stack costs. There are no papers refuting this claim.
