How do batteries differ from cells? What arrangement of three cells will result in the greatest electric current? Which arrangement would result in the greatest longevity (lasts longest) for the battery?
Describe three factors within a voltaic cell that you could manipulate in order to produce a cell with the highest possible voltage. For each factor describe how you would manipulate it.
Describe the advantages and disadvantages for using fuel cells compared to other types of electrochemical cells.

A 1.5V AA is a cell, because it is a singular voltaic arrangement. A 9V is a battery, because it contains 6 x 1.5V cells in series. Same with car batteries.....they contain several cells. So battery is just the plural form of a cell.
A parallel arrangement of 3 cells would produce the most current, where all of the positive terminals are connected together, and all of the negative terminals are connected together.
A parallel arrangement of 3 cells would produce the most longevity, where all of the positive terminals are connected together, and all of the negative terminals are connected together.
To get maximum voltage, you have to change to a more energy-dense chemistry. Lithium ion cells have at least double the voltage of alkaline or Ni-MH.
Fuel cells will produce forms of energy that produce more power than conventional electrochemical cells, because now we're talking about hydrogen, in which the energy density is much higher.

1) A battery is a cell. Sometimes they are 'ganged up' inside a package to produce more voltage, such as a 9 volt 'square' battery.
2) Current - parallel
3) Not related - depends on current draw....
