No, the anode is the positive electrode in a hydrogen-oxygen fuel cell. At the anode, hydrogen gas is oxidized to produce protons and electrons. The electrons flow through an external circuit to the cathode, where they combine with oxygen and the protons to form water.

When electric current pass through water.Which gases r obtained as anode and which obtain as cathode?
When an electric current passes through water, hydrogen gas is obtained at the cathode (negative electrode) and oxygen gas is obtained at the anode (positive electrode) through the process of electrolysis.
What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
When electrolysis is performed on a dilute sodium chloride solution using copper and zinc electrodes, chlorine gas will be produced at the anode (positive electrode) and hydrogen gas will be produced at the cathode (negative electrode). At the same time, sodium hydroxide solution will be formed in the solution. The copper electrode will remain unaffected, while the zinc electrode may corrode due to hydrogen evolution reactions.
What do you call the electrode connected to negative terminal of a cell?
The electrode connected to the negative terminal of a cell is called the cathode.
What are the two gases used to produce electricity in fuel cells?
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
When the switch is closed which electrode will attract the sodium ion?
When the switch is closed, the positive electrode (anode) will attract the sodium ion. Sodium ions have a positive charge, so they will be attracted to the negative charge on the anode.
When electric current pass through water.Which gases r obtained as anode and which obtain as cathode?
When an electric current passes through water, hydrogen gas is obtained at the cathode (negative electrode) and oxygen gas is obtained at the anode (positive electrode) through the process of electrolysis.
Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
When an electric current passed through water which gas is obtained on anode?
The anode is the negative electrode. It produces hydrogen gas.
What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
When electrolysis is performed on a dilute sodium chloride solution using copper and zinc electrodes, chlorine gas will be produced at the anode (positive electrode) and hydrogen gas will be produced at the cathode (negative electrode). At the same time, sodium hydroxide solution will be formed in the solution. The copper electrode will remain unaffected, while the zinc electrode may corrode due to hydrogen evolution reactions.
What will happen when electric current pass through water?
When electric current passes through water, electrolysis occurs, breaking down water into its constituent elements of hydrogen and oxygen gas. The hydrogen gas is produced at the cathode (negative electrode), while oxygen gas is produced at the anode (positive electrode).
What is a positive electrode?
A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
What is the negative electrode of a voltaic cell called?
The negative electrode of a voltaic cell is called the anode. It is where oxidation occurs as electrons are released into the circuit.
What is meant by anode and cathode?
Anode is positive electrode which attracts the negative anions while cathode is the negative electrode which attracts the positive cations during electrolysis.
What do you call the electrode connected to negative terminal of a cell?
The electrode connected to the negative terminal of a cell is called the cathode.

When the switch is closed which electrode will attract the sodium ion?
When the switch is closed, the positive electrode (anode) will attract the sodium ion. Sodium ions have a positive charge, so they will be attracted to the negative charge on the anode.
How do you decompose water into hydrogen and oxygen?
Water can be decomposed into hydrogen and oxygen through a process called electrolysis. This involves passing an electric current through water, which causes the water molecules to split into hydrogen gas at the cathode and oxygen gas at the anode. This process requires a source of electricity and special electrodes to facilitate the reaction.
