Abstract
The disclosure provides a fuel device for an automobile, an automobile with the fuel cell device and a method for operating the fuel cell device. The fuel cell device comprises a first pipe, a second pipe, and a pressure regulator. The first pipe connects a gas tank to a fuel cell. The second pipe connects the fuel cell with an open end of the second pipe. The fuel cell is arranged to be driven by evaporated liquefied gas contained the gas tank. The pressure regulator is arranged to control the evaporation of the liquefied gas.
Claims13
A fuel cell device for an automobile comprising:
- a first pipe, wherein the first pipe connects a gas tank to a fuel cell, the gas tank configured to store liquefied gas;
- a second pipe having an open end and connected to the fuel cell;
- and
- a pressure regulator,
- wherein the fuel cell is arranged to be driven by evaporated liquefied gas from the gas tank, and wherein the pressure regulator is arranged to control the evaporation of the liquefied gas, and
- wherein, at a parking mode or an idle mode, the pressure regulator is configured to supply the evaporated liquefied gas from the gas tank to the fuel cell when a pressure of the evaporated liquefied gas in the gas tank is higher than or equal to a predetermined pressure value, and not to supply the evaporated liquefied gas from the gas tank to the fuel cell when the pressure of the evaporated liquefied gas in the gas tank is lower than the predetermined pressure value.
A fuel cell device for an automobile comprising:
- a first pipe, wherein the first pipe connects a gas tank to a fuel cell, the gas tank configured to store liquefied gas;
- a second pipe having an open end and connected to the fuel cell;
- and
- a pressure regulator;
- wherein the first pipe includes a first valve that is arranged between the fuel cell and the pressure regulator;
- wherein the second pipe includes a compressor and a second valve, wherein the compressor is arranged between the open end of the second pipe and the second valve;
- wherein the first pipe further includes a further compressor or a further regulator arranged between the first valve and the pressure regulator;
- and
- wherein the fuel cell is arranged to be driven by evaporated liquefied gas from the gas tank, and wherein the pressure regulator is arranged to control the evaporation of the liquefied gas.
