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.
Electrons flow from the negative electrode (cathode) to the positive electrode (anode) in an electrolytic cell. This is the opposite direction of conventional current flow.
A "cell" (word for part of a battery) is a source of current flow.A diode is a device that restricts current flow to one direction.
When the flow of current is aways in one direction it is known as direct current.
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
direction of magnetic field
A negative answer in a Kirchhoff's Current Law calculation indicates that the assumed direction of current flow was incorrect. It suggests that the actual direction of current flow is opposite to the assumed direction. Therefore, the sign of the calculated current should be corrected to reflect the actual flow direction.
Current flows from the positive terminal (anode) to the negative terminal (cathode) inside a cell or battery. This flow of electric charge is due to the movement of electrons through the external circuit connecting the two terminals.

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. ]
A current consisting of charges that flow only in one direction is called direct current (DC). In DC, electrons flow continuously in one direction from the negative to the positive terminal of a power source.
Direct current (DC) does not reverse its direction of flow. This means that the flow of electrical charge in a DC circuit always moves in one direction, from the positive terminal to the negative terminal.
Current Density describe how charge flow at certain point since current density = I/A and the vector direction tells you about the direction of flow at that point.
