Ultra-pure hydrogen is required in applications rang- ing from the manufacturing of semiconductors to powering fuel cells. The crystalline structure of palla- dium allows only the transfer of atomic hydrogen (H) through its thickness, and therefore palladium mem- branes are used to filter hydrogen from contaminated streams containing mixtures of hydrogen and other gases. Hydrogen molecules (H) are first adsorbed onto the palladium's surface and are then dissociated into atoms (H), which subsequently diffuse through the metal. The H atoms...

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: O a. hydrogen fuel cells can produce more energy than is used to create the hydrogen by...

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...

We know already that a typical household uses about 1000 kWh of energy in one month. Let's investigate the advantages of nuclear energy by considering the following problem: if you were given a gallon of water, how long could it supply fusion energy for your home? In this case, you are considering a fusion reaction between two deuterium nuclei which releases 4.0 MeV. We will follow this problem through to the end in stages. Part I: How many deuterium nuclei...
