The high efficiency of fuel cells is attributed to their direct conversion of chemical energy into electrical energy through electrochemical reactions. This process is highly efficient, especially when compared to the multiple energy conversion steps in internal combustion engines. However, it's important to note that the actual efficiency can vary depending on factors such as temperature, pressure, and the specific fuel cell design.

To put this into perspective, let's consider a hypothetical fuel cell car with a fuel consumption rate of 1 kilogram of hydrogen per 100 kilometers. If this car were to travel 1000 kilometers, it would consume 10 kilograms of hydrogen, generating a total power output of 1000 to 1500 watts during that journey. This translates to a continuous power output of approximately 10 to 15 horsepower, which is quite impressive for a vehicle with zero direct emissions.

In summary, fuel cell efficiency is a key factor in the development of sustainable transportation.
