Abstract

The invention relates to a fuel cell without electrolyte, which comprises a single reaction body component or a dual reaction body component. Two outer side faces of the reaction body component are respectively provided with a collector, the reaction body component and the collectors are arranged in a shell, one side of the shell is respectively provided with an air inlet and an air outlet, and the other side of the shell is respectively provided with a hydrogen inlet and a hydrogen outlet. The fuel cell without electrolyte provided by the invention uses a simple method to form a device of the single reaction body component or the dual reaction body component which replaces a construction of three components, i.e. an anode, a cathode and electrolyte of the traditional fuel cell, and electrical energy conversion of the fuel cell can also be achieved. By using the novel fuel (conversion from chemical energy to electrical energy) device technology, the problems of high cost and limitation on commercialization of the fuel cell due to difficult and complex technology can be fundamentally solved, and industrialization and commercialization of the fuel cell can be fast realized.

Description

technical field [0001] The invention belongs to the technical field of energy conversion, and in particular relates to a fuel cell device for converting chemical energy into electrical energy. Background technique [0002] All current fuel cells follow the three-component structure of anode 8-electrolyte 9-cathode 10 invented by GROVE 170 years ago, see image 3 , the so-called MEA (membrane electrode assembly) technology. Among them, the electrolyte is a key component. It is a pure ionic conductor used in fuel cell diaphragms to isolate the anode and cathode to prevent fuel cell short circuits, and to transport ions to achieve fuel cell reactions and convert electrical energy. The higher the purity of the ion conductivity of the electrolyte, the better. Generally, it needs to be more than 90%-98. Any electron conduction will cause the fuel cell to leak electric energy and reduce the fuel cell's electric energy conversion efficiency. Due to the limitations of electrolyte m...
