Concept explainers
(a)
Interpretation:
A parallel lists for the advantages and disadvantages of using hydrogen as the fuel for transportation and for producing electricity have to be set up.
Concept introduction:
A Fuel is a substance that releases energy when it gets burnt in presence of Oxygen. The phenomenon a substance getting burnt in presence of Oxygen is termed as combustion and it is exothermic process. The larger the amount of heat released per gram of a substance, greater the potential it has to be a fuel.
PEM fuel cell: These cells work with a
(b)
Interpretation:
Hydrogen as fuel for both transportation and electricity production has to be explained as an article.
Concept introduction:
Fuel cell: The fuel cell is a device, which converts the chemical energy into
For example Hydrogen-Oxygen fuel cell, in this cell, Hydrogen is a fuel and Oxygen is an oxidant. The continuous flow of fuel and oxidant is gives a continuous production of current.

Chemistry In Context
- 9.69 How are the roles of transmission substations and distribution substations in the electrical grid similar? How are they different?arrow_forwardThe best solar panels currently available are about 15% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh = 1 kilowatt hour; 1kW = 1000 J/s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical homes electricity. (See Exercise 124 for the energy rate supplied by the sun.)arrow_forwardFossil fuel, nuclear, and hydroelectric power plants all require a transmission network to transport electricity from where it is generated to where it is used. MCFCs, with their smaller size and portability, can be placed much closer to where the power is needed, reducing the need for transmission lines. With this in mind, explain why MCFCs may have a greater advantage for providing power in developing countries versus in developed countries.arrow_forward
