The solutions' concentration must be at 1.0 mol.dm-3 (mol per cubic decimeter) Gases' pressure must be at 1 atm, in other words, 101.3 kPa The temperature of gases and solutions must be at 298 Kelvin.
The Anode in electrochemical cell has negative charge (-ve).
A voltaic cell is also called a Galvanic Cell. It is an electrochemical cell, but unlike other electrochemical cells it uses spontaneous redox reactions to create electricity.
Lots of things have an electrochemical cell in them. That electrochemical cell is a battery. You cell phone has at least two of them. There is a small one that "keeps alive" memory if you remove the primary battery. A flashlight has a cell or cells in it. We could go on all day. Motor vehicles have a battery, which is a collection of electrochemical cells. Note that a battery could be composed of a single cell, like the "AAA", "AA", "C" and "D" cells. We call them batteries, but they are a single electrochemical cell. A 9-volt battery, on the other hand, has several cells in it stacked in series so their voltages add. That car battery we mentioned is 6 electrochemical cells "long" so that the voltages will sum to the 12 volts (which is actually a bit over 13 volts).
The first electrochemical cell was invented by Alessandro Volta in 1800. This cell, known as the Voltaic pile, consisted of alternating discs of zinc and copper separated by cardboard soaked in salt water.
Electrons enter an electrochemical cell through the anode. The anode is where oxidation occurs, leading to the release of electrons that flow through the external circuit to the cathode.

true
In an electrochemical reaction, the cell can be positive or negative, depending on the direction of electron flow.
