Abstract

The invention provides a fuel cell humidification system which comprises an electric pile and an air-air intercooler, and the electric pile is connected with a circulating hydrogen inlet assembly through a pipeline; the two sides of the air-air intercooler are detachably connected with a flowing type air transmission assembly, and the middle part of the flowing type air transmission assembly is detachably connected with the electric pile; a circulating water assembly is arranged between the air-air intercooler and the electric pile, and one end of the circulating water assembly is detachably connected with the circulating hydrogen inlet assembly. According to the invention, the structure is more compact through connection of the circulating water assembly and the air-air intercooler, and meanwhile, water and hydrogen are recycled, so that more energy is saved.

Description

technical field [0001] The invention relates to the technical field of fuel cell humidification, and mainly relates to a fuel cell humidification system. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Because fuel cells are The Gibbs free energy in the chemical energy of the fuel is partially converted into electrical energy through an electrochemical reaction, which is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials; at the same time, there are no mechanical transmission parts , so there is no noise pollution, and very little harmful gas is emitted. It can be seen that from the perspective of energy saving and ecological environment protection, fuel cells are the mo...
