A carbon dioxide self-exhaling battery anode device of a liquid fuel cell

Abstract

The invention discloses a carbon dioxide self-exhalation cell anode device of a liquid fuel cell, and the device is capable of overcoming the weaknesses of the prior art that performance of the fuel cell is influenced by the incapability of discharging the carbon dioxide generated by the liquid fuel cell, and provides a carbon dioxide self-exhalation cell anode device of the liquid fuel cell capable of preventing the accumulation of carbon dioxide. The carbon dioxide self-exhalation cell anode device comprises a passage wall, a gas diffusion electrode, a gathering cavity wall and a check valve, wherein the gas diffusion electrode is arranged in the passage wall in a penetrating manner, the gathering cavity wall is arranged outside the gas diffusion electrode, the gathering cavity wall is installed on the passage wall, a carbon dioxide gathering cavity is separately formed between the gathering cavity wall and the passage wall and between the gathering cavity wall and the gas diffusion electrode, and the check valve is arranged on the gathering cavity wall in a penetrating manner. By adopting the carbon dioxide self-exhalation cell anode device, the effect of eliminating the accumulation of carbon dioxide bubbles in a fuel cell passage is achieved. The carbon dioxide self-exhalation cell anode device has the advantage that the parasitic reaction of the gas diffusion electrode on the surface of the anode is inhibited. The carbon dioxide self-exhalation cell anode device is suitable for the field of the liquid fuel cell.

Description

technical field [0001] The invention belongs to the field of liquid fuel cells, in particular to a carbon dioxide self-exhaling battery anode device of a liquid fuel cell. Background technique [0002] A fuel cell is a power generation device that directly converts the chemical energy present in fuel and oxidant into electrical energy. The fuel and air are fed into the fuel cell separately and react to generate electrical energy. In fact, it cannot "storage electricity" but a "power plant". [0003] Fuel cells are environmentally friendly. It works through electrochemical reactions rather than burning or storing energy. At the same time, the power generation efficiency of the fuel cell can reach more than 50%, which is determined by the conversion properties of the fuel cell, which directly converts chemical energy into electrical energy without intermediate conversion of thermal energy and mechanical energy. [0004] For fuel cells using liquid organic matter as fuel in ...
