Abstract
An air and liquid separator used in a fuel cell, the air and liquid separator including: a fuel guidance pipe having one or more opening portions on a surface thereof; and an air and liquid separating film provided on the opening portions of the fuel guidance pipe and transmitting only gas. Accordingly, an air and liquid separator according to aspects of the present invention remove gas included in non-reactive fuel by using an air and liquid separating film, without any separate power sources, and supplies the non-reactive fuel to a fuel cell, enabling a more compact and high efficient fuel cell system.
Claims20
An air and liquid separator used in a fuel cell releasing non-reactive liquid fuel and a gas, the air and liquid separator comprising:
- a fuel guidance pipe receiving the non-reactive liquid fuel and the gas and having one or more opening portions on a surface thereof;
- and
- an air and liquid separating film provided on each of the opening portions of the fuel guidance pipe and transmitting only the gas to an outside of the fuel guidance pipe.
A fuel cell system comprising:
- a fuel vessel to store liquid fuel;
- a fuel mixer to generate mixing fuel by mixing the fuel and water;
- an electricity generating unit to generate electricity through an electrochemical reaction by using the mixing fuel and oxygen;
- and
- an air and liquid separator to separate gas and a non-reactive fuel, which is the mixing fuel that is not reacted in the electrochemical reaction, exhausted from the electricity generating unit, the air and liquid separator comprising:
- a fuel guidance pipe receiving the non-reactive fuel and the gas and having one or more opening portions on a surface thereof, and
- an air and liquid separating film provided on each of the opening portions of the fuel guidance pipe and transmitting only the gas to an outside of the fuel cell system.
