Embodiment 1

[0035] Such as figure 1 , figure 2 As shown, this embodiment provides a hydrogen fuel cell bus, such as a bus, a minibus, etc., including a bus body 1, and a wheel assembly 11 is provided at the bottom of the bus body 1, and the wheel assembly 11 includes two wheels. and the main beam connecting the two wheels. The main body of the passenger car 1 is provided with a plurality of seats for passengers to sit on. The central main control board for the operator to check and operate, the rear part of the passenger car main body 1 is provided with an equipment compartment 12 under the seats in the rear row, and the fuel cell engine 2 is arranged in the equipment compartment 12, and the passenger car main body 1 Both sides of the rear part in the interior are provided with detachable shutters 13 communicating with the equipment compartment 12. The equipment compartment 12 includes an outer frame 121 and a coaming plate 122 installed on the top and front of the outer frame 121. The...

Embodiment 2

[0041] Such as Figure 4 , Figure 5 , Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the top of the bus body 1 is provided with a high-pressure hydrogen storage system 4 facing the fuel cell engine 2, and the high-pressure hydrogen storage system 4 includes a protective cover 41 and The hydrogen storage module, the hydrogen filling module and the hydrogen supply module located in the protective cover body 41, the hydrogen filling module is connected to the hydrogen storage module through a hydrogen pipeline, and the hydrogen storage module is connected to the hydrogen pipeline through a hydrogen pipeline. A hydrogen supply module, the hydrogen supply module is connected to the fuel cell engine 2 through a hydrogen pipeline;

[0042] The hydrogen filling module includes a filling port 422, a filter 423, a one-way valve 424 and a mechanical pressure gauge 425, and the hydrogen storage module includes a hydrogen storage bottle 426 and a bot...

Embodiment 3

[0058] The difference between this embodiment and the previous embodiment is that, if Figure 7 As shown, the fuel cell engine 2 includes a DC converter 21, an expansion kettle, a deionizer, a membrane humidifier 22, an intercooler 23, an electric stack 24, and an air filter element arranged sequentially along the width direction of the passenger car body 1. 25. Air compressor 26, air compressor controller 27, hydrogen inlet nozzle, high-pressure water pump and electric drive block 28, expansion kettle, deionizer, hydrogen inlet nozzle and high-pressure water pump are not shown in the figure. Wherein, the DC converter 21 includes two parts of converting from low voltage to high voltage and converting from high voltage to low voltage, and the fuel cell engine 2 also includes some system pipelines required for heat dissipation such as the electric stack 24 .

[0059] The above-mentioned components are arranged in a flat manner, which is conducive to reducing the height of the fu...

Abstract

The invention discloses a hydrogen fuel cell passenger car, which comprises a passenger car body. The passenger car body is provided with wheel assemblies, seats and a cockpit; an equipment cabin is arranged below rear-row seats of the passenger car body; detachable shutters are arranged on the two sides of the tail part of the passenger car body; the equipment cabin comprises an outer frame and coamings installed on the top and the front portion of the outer frame; a fuel cell engine is arranged in a space defined by the outer frame; the coaming is a transparent plate or a transparent visualopening capable of observing the fuel cell engine is formed in the coaming; the rear-row seat comprises a mounting bracket and a cushion detachably connected with the mounting bracket; a hollow part capable of observing the fuel cell engine through the coaming or the transparent visual opening is formed in the mounting bracket; a lithium battery is arranged in the passenger car body between the two wheel assemblies; the lithium battery is electrically connected with the fuel cell engine; and a visible window which is communicated with the equipment cabin and can be used for observing the fuelcell engine and the lithium battery is formed in the rear side face of the passenger car body. The hydrogen fuel cell passenger car is high in visualization degree, can facilitate supervision and maintenance, and is good in safety.

Description

technical field [0001] The invention relates to the technical field of passenger cars, in particular to a hydrogen fuel cell passenger car. Background technique [0002] With the deteriorating climate and the frequent occurrence of smog and haze in recent years, environmental protection has become a hot topic, and the relationship between the environment and people has become more and more tense. There is a non-negligible problem in environmental pollution-motor vehicles burn a large amount of fossil fuels, and vehicle exhaust emissions account for a large part, and it is increasing day by day. The development of new energy vehicles is imperative. As the ultimate direction of new energy vehicles, fuel cells are completely pollution-free in terms of energy sources and waste generation, and are the most ideal development trend of new energy vehicles. At present, the development of fuel cells in my country has entered a stage of rapid development. Hydrogen fuel cells, a more a...
