Working principle of h2-o2 fuel cell?
Polymer Electrolyte Membrane (PEM) fuel cells used in automobiles-also called Proton Exchange Membrane fuel cells-use hydrogen fuel and oxygen from the air to produce electricity. The diagram to the right shows how a PEM fuel cell works.Most fuel cells designed for use in vehicles produce less than 1.16 volts of electricity-far from enough to power a vehicle. Therefore, multiple cells must be assembled into a fuel cell stack. The potential power generated by a fuel cell stack depends on the number and size of the individual fuel cells that comprise the stack and the surface area of the PEM.
What is the part of the cell that is a stack of membranes?
tubular cells
What are the vertical cells called in a table?
A vertical stack of cells is called a column. A horizontal line of cells is called a row.
What are the four major types of cells?
Polymer electrolyte fuel cells (PEFCs)PhoMolten carbonate fuel cells (MCFCs)sphoric-acid fuel cells (PAFCs)Solid oxide fuel cells (SOFCs)
How are fuel cells categorized?
explain how fuel cells are commonly categorized
When was Ceramic Fuel Cells created?
Ceramic Fuel Cells was created in 1992.
What is Ceramic Fuel Cells's population?
Ceramic Fuel Cells's population is 150.
Is hydrogen fuel cells fossil fuels?
no because hydrogen fuel cells are renewable
How could fuel cells give space crews electricity and water?
fuel cells converts chemical energy to eletrical power and the only waste product for fuel cells is water
What are some pros and cons of fuel cells?
Some pros of fuel cells are that it is: -efficient -produces no odor, no noise -reliable -environmentally friendly -is indefinetely renewable, as long as hydrogen is harvested Some cons of fuel cells are: - fuel cells are expensive -you have to harvest hydrogen, which is hard -The volume of the fuel cells are larger than the average internal combustion engine.
Can you give an example of a sentence using stack?
"Stack those boxes over here", said the receiving clerk. I could eat a mile high stack of flapjacks! When an airport has a traffic jam in the sky, the controllers stack the incoming arrivals according to how much fuel each airplane has left.
Why do plant cells have rectangular shape?
so they can stack up high and be tall like trees
