Is hydrogen fuel-injection more potent than hydrogen fuel cell? - fuel cell concept
BMW has a car with hydrogen injection flow, ie it is not a hydrogen fuel cell but uses the same engine to burn gasoline, but now it burns the hydrogen in its place. The car is here.

I wonder, what if the hydrogen gas when it burns the engine as gasoline is powerful, which requires a fuel injection, is a stronger fuel cell itself? My particular interest if the two different energies (cons cell battery combustion) of hydrogen. When the combustion of hydrogen produces more electricity, while the additional energy to compensate theory for the loss of 30-40 percent of the energy in hydrogen production.
What is used, the difference in energy (electricity) by the combustion of hydrogen in a fuel injection (combustion) engine and hydrogen in power generation in fuel cells, hydrogen? The power of gasoline is higher.

Fuel Cell Concept Is Hydrogen Fuel-injection More Potent Than Hydrogen Fuel Cell?

The key is when you make the loss of efficiency 30 Report to 40 percent, the hydrogen in the first place, there is no way this loss of efficiency, even back when they achieved a 100% hydrogen itself efficiently.

Internal combustion engines since fuel efficiency is 50% (ideal), and may be internal) up to 30% efficiency (ideally, would fuel still win. But combine that with the loss of the conversion of hydrogen, and the best we can hope for, an overall yield of 35%.

I will do something unexpected, and compare it with an electric car. It is true that half of our electricity comes from coal, but very efficiently the fuel is burned in power plants and large (about 85% loading efficiency in new facilities.) Energy transmission by wire to cars to Electric is 95% efficiency (number, how many times the efficiency of the gasoline truck was lost in the whole country.) Battery storage is about 90% efficiency and electric motors are also nearly 95% efficiency.
*
Multiplying these numbers gives us a performance of aBout 69%. But the number is even better than that because not all electricity comes from fossil fuels, and EVS can also recover energy during braking to recharge the battery when it shuts down.

This electric car is almost forgotten poor, but progress on the batteries have been in recent years. Check out this vehicle:

The Phoenix may be up to 250 miles per charge, which loads a minimum of 5 passengers and cargo to 95 km / h, the battery in just 10 minutes, and last longer than 200,000 miles (for the lifetime of the car.) Yes, it is a real Date car, purchase orders and begin to build the cars in this month.
