A thermocouple is a device which generates an electrical charge when heated. It is often used on a boiler to indicate that the pilot light is on and hot, so it should be safe to allow gas to pass to the main burner for heating water, your house, etc. Should the pilot light go out, the thermocouple will sort of "tell" the boiler to shut off the gas, as it isn't safe to fire up. A thermostat is used as a switch, which goes on and off at a certain temperature. For example, in a boiler it will tell the boiler that the water in the circuit is plenty hot enough and that it doesn't need to be heated any more, in your house it will tell your central heating that the room is warm enough and doesn't need heating any more and in your car it would say that your engine is too hot and that the radiator valve should open, and perhaps the cooling fan should turn on.
