"There are many problems associated with fuel cells. For instance, most of the components used are expensive and hence they defeat the purpose in terms of costs involved. To be cost effective and to withstand the market competition, they have to be priced at $35 per kilowatt. Presently however, the production price is $ 110 per kilowatt, that works out to $75 more than gasoline powered vehicles. This is an expensive proposition." (Quoted from article)
