After text activity
I. Reading Exercises:
Exercise 1. Read and memorize using a dictionary:
|
Reactant, storage, distribution, fuel, cell, cabin, pressurization, bus |
Exercise 2. Answer the questions:
What does each fuel cell power plant consist of?
Where is the excess heat directed?
Where are the hydrogen and oxygen stored?
What is each assembly?
Exercise 3. Match the left part with the right:
1. The PRSO subsystem stores a) heat and water
2. The EPS consists of b) the reactants
3. Each fuel cell power plant c) three subsystems
consists of
.
4. The fuel cell power plants d) a power section
generate
Exercise 4.
The excess heat is (collected/directed) to fuel cell (heat/power) exchanger, where the excess (water/heat) is rejected to Freon coolant loops.
II. Speaking Exercises:
Exercise 1. Describe power bus, fuel cell power plants, store, PRSO subsystem using the suggested words and expressions as in example:
Power bus
Assembly, contains, remote switching devices, subsystems, located in
Example:
Each assembly usually contains a power bus or buses and remote switching devices for distributing bus power to subsystems located in its area.
Fuel cell power plants
Three, coupled to, subsystem, heat, storage, EPDC
Store
Hydrogen, oxygen, respective storage tanks, temperatures, pressures
PRSD Subsystem
Stores, reactants, supplies, generate, electrical power, vehicle
Exercise 2. Ask questions to the given answers:
1) Question: ___________________________________________ ?
Answer: The storage temperature of liquid oxygen is minus 285 F.
2) Question: ___________________________________________ ?
Answer: The fuel cell power plants generate heat and water as by products of electrical power generation.
3) Question: ___________________________________________ ?
Answer: Power is controlled and distributed by assemblies.
4) Question: ___________________________________________ ?
Answer: E ach assembly usually contains a power bus or buses and remote switching devices for distributing bus power to subsystems located in its area.
