Description

technical field [0001] The invention relates to the field of direct carbon fuel cell preparation, in particular to a carbon fuel cell coal-based fuel joint processing device and a processing method thereof. Background technique [0002] Fuel cells (fuel cells, FCs) are the fourth-generation power generation technology after thermal power, hydropower and nuclear power. It is considered to be the most promising high-efficiency and clean power generation technology in the 21st century. As a kind of fuel cell, direct carbon fuel cell DCFC can use graphite, activated carbon, coal coke, biomass coke, etc. as fuel. Carbon (carbon derivatives) and oxygen undergo electrochemical reactions to generate electricity directly without gasification. It has the characteristics of high energy conversion efficiency, cleanliness and wide fuel adaptability. The operating temperature of direct carbon fuel cells is between 400 and 1000°C. [0003] Direct Carbon Fuel Cell DCFC uses carbon as fue...

Problems solved by technology

However, the first step is more complicated, which increases the cost of the entire carbon fuel cell itself. The second is that the electrochemical oxidation process occurs in the electrolyte, which easily affects the entire chemical reaction process and destroys the activity of the cathode and anode.
