A friend argues that there’s plenty of hydrogen available for fuel- cell vehicles; just look at all the H2O in the ocean. Refute this argument.
Homework Answers
It is true that there is plenty of H2O in ocean. But to extract the hydrogen from water molecule we need to do the electrolysis of water which itself require electricity.

Some hydrogen fuel cell vehicles fill up at a gas station that uses hydrolysis to produce the hydrogen gas. When hydrogen is combined with oxygen in the fuel cell, energy is released to power the car. The reaction is like hydrolysis in reverse 2H2O (liq.) + energy ← 2H2 (gas) + O2 (gas) Pick all statements which are true. Select one or more: a. using hydrogen made by electrolysis is more efficient and cleaner than using the fuel or electricity...

Hydrogen (H) and oxygen (O.) are reacted in a fuel cell to produce energy. The product of the reaction is water, and any excess gases are vented after the fuel cell, as shown in the figure below. The hydrogen and oxygen tanks are maintained at the same temperature and pressure, and they feed at the same volumetric flow rate. The reaction goes to 60% completion in the fuel cell (hydrogen basis) If all of the unreacted hydrogen and a portion...

Zipcar: “It’s Not About Cars—It’s About Urban Life” Imagine a world in which no one owns a car. Cars would still exist, but rather than owning cars, people would just share them. Sounds crazy, right? But Scott Griffith, CEO of Zipcar, the world’s largest car-share company, paints a picture of just such an imaginary world. And he has nearly 800,000 passionate customers—or Zipsters, as they are called—who will back him up. Zipcar specializes in renting out cars by the hour...
