i also need to no how expensive it is to buy it. im doing a project for school.
I don't know the exact price of it; however, it is priced higher than regular gasoline because it is newer technology.
its not only the matter of expense how safe is it ? that is the concern better take help of a specialist
Hydrogen fuel cells of the commonly used PEM type cost between $1500 and $2500 per kilowatt, depending on manufacturer and application. A typical car needs at least a 75 kW fuel cell, which would typically cost around $150,000. The hydrogen would cost about the same per mile as gasoline. More, once government starts taxing it. This is also hydrogen produced from natural gas, which actually emits more CO2 than using gasoline in a combustion engine. If produced from electricity, hydrogen costs about 2 times as much per mile, but might ultimately emit less CO2. If used as a liquid (instead of a compressed gas), it costs another 1.5 times as much per mile (and emits that much more CO2). If the application is backup electric power, a typical home would need about 6 kW. So a hydrogen fuel cell for a house would cost about $12,000, plus another $2,000 for the inverter and transfer switch. Again, the cost of operating a hydrogen genset verses a gasoline genset is similarly comparable to the difference in hydrogen as a motor fuel vs gasoline. A natural gas genset is definitely less expensive, in fuel, equipment, and pollution.
