Current doesn't flow inside the cell. The cell is used to push current through an external
circuit.
The so-called "conventional" current flows out of the positive terminal of the cell, through
the circuit, and back into the negative terminal of the cell.
The confusing truth is that the actual physical carrier of current is the electron, which
carries a negative charge. So the things that are actually moving and carrying the current
through the circuit leave the dry cell from its negative terminal, physically flow through
the circuit, and end up at the cell's positive terminal.
A diode is one of the fundamental building blocks of electronics. They allow the flow of electrons in one direction only. Thus are commonly used as rectifiers to turn ac voltages into dc. [A dry cell (mistakenly called a battery, which is a group of cells) will allow electron flow in one direction only, or rather, it will provide current flow in one direction. ]

an acid paste reacts with the metal casing which causes electrons to flow to a carbon rod
A dry cell battery has the electrolyte immobilized as a paste, with only enough moisture in it to allow current to flow. A dry cell can operate in any orientation without spilling as it contains no free liquid.
A dry cell produces direct current, which means that the current flows from one terminal of the dry cell to the other in one direction only. The word generator nowadays often means a device that produces alternating current, which is to say current that reverses its direction, usually at a fixed rate called the frequency. For instance, the current available in North American homes is alternating current at 60 cycles per second; it reverses direction 120 times per second. A machine that produces current that resembles what is available from a dry cell is often called a dynamo. These devices are similar to generators but with switches in them to change the alternating current to direct current, in effect. The current they produce is still not quite like that from a dry cell inasmuch as it's not perfectly 'smooth' continuous direct current. There's a ripple of slightly higher and lower current superimposed on the direct current. Please see the link, especially the graph associated with the Gramme dynamo.
A dry cell battery does not use current it produces a current when connected to an electrical load. The type of current that the dry cell produces is DC (direct current).
The current produced by batteries is direct current. Electronic devices need direct current; in this case, they need a power supply (often built into the electronic device itself), that converts the alternating current, from the electric outlet, to direct current.
directA dry cell battery produces DC.
The voltage will be double that of one dry cell. The current will be that of one dry cell.
A Direct Current, DC.
It is DC or `direct current'.
