摘要:
A liquid fuel mixer is disclosed, which is used to store liquid fuels for a fuel cell. The liquid fuel mixer includes a casing, one or more radiators and a gas permeable but liquid impermeable film. The casing forms a first internal compartment and a second internal compartment, and the first internal compartment is adjacent to the second internal compartment. The casing next to and separating the first internal compartment from the second internal compartment includes at least one vent and at least one drain. The second internal compartment contains the liquid fuels. The radiators are disposed in the first internal compartment. The gas permeable but liquid impermeable film is disposed on the vent. To avoid water condensing on the walls, the bottom of the first internal compartment includes a slopping channel and/or a flow-guilding channel, and the drain is disposed on the end of the lower portion of the slopping channel or the flow-guilding channel.

The present invention is a pressure relief valve structure with pressure relief seam, which is composed of the pipe, and the elastic plug with the edge tightly attached on the pipe wall of the pipe, and the elastic plug is penetrated with slim seam. When the fluid is flowing to the elastic plug through the pipe, and the impact pressure from the fluid is larger than the slim seam of the elastic plug could resist, the intersection along the slim seam would be deformed as a hole to make the fluid flowing through the elastic plug and achieve the purpose of pressure relief.
