Overhead type bus fuel battery motor ventilating dustproof and rainproof design

Abstract

The invention relates to an overhead design for a fuel-cell generator of a bus, which is airy, dustproof and rainproof. The fuel-cell generator is arranged on the top of the bus and a sheet metal of a vehicle shell on the top of the generator is designed to be a louver shape. The louver comprises multiple sets of single sheets; thereof the single sheet consists of a sheet and a groove connected with the lower part of the sheet. A narrow and long gap is arranged among the grooves and a dustproof net is arranged under the grooves. The vehicle shell at the both sides of the louver is provided with a plurality of intakes which can also be designed to be the louver shape; thereof an obtuse angle is formed between the sheet direction and the running direction to prevent the rainwater enters when the car is running. The dustproof net is arranged inside of the intakes. Compared with the prior art, the invention can not only cover and protect a coping of the bus but also play an airy, dustproof and rainproof role.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a ventilating, dustproof and rainproof design for a top-mounted bus fuel cell engine. Background technique [0002] An electrochemical fuel cell is a device that converts hydrogen and oxidants into electrical energy and reaction products. The internal core component of the device is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode (MEA) is composed of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched between the two sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are even and finely dispersed catalysts for initiating electrochemical reactions, such as metal platinum catalysts. Conductive objects can be used on both sides of the membrane electrode to draw the electrons generated during the electrochemical reaction through an external circuit to form a curren...

AI Technical Summary

Problems solved by technology

The shortcomings of using the existing internal combustion engine engine space of the existing city bus, that is, the front compartment or the rear compartment, are very obvious, and the design is difficult

[0017] (1) Whether the internal combustion engine of the existing city bus is front or rear, the space is very irregular, and the assembly is very difficult;

[0018] (2) Fuel cell engines are quite different from traditional internal combustion engines in terms of structure, shape, and size, and cannot be easily replaced in the original space of city buses

[0019] At present, the engine of the roof-mounted fuel cell bus is enclosed and wrapped on the top of the bus. If there is hydrogen leakage, it is easy to accumulate in the warehouse, which is prone to explosion, and the design of perforated or ordinary shutters cannot achieve waterproof effect.
