What are the types of fuel-powered batteries? How does it work?

At present, there are many types of fuel lithium batteries, and there are many ways to classify them. According to different methods, it is roughly classified as follows: (1) According to the operating mechanism: it can be divided into acidic fuel lithium batteries and alkaline fuel lithium batteries; (2) according to the type of electrolyte: there are acidic, alkaline, molten salt or Solid electrolyte; (3) Classified by fuel type: direct fuel lithium battery and indirect fuel lithium battery; (4) according to the working temperature of fuel lithium battery: low temperature type (below 200 ℃); medium temperature type ( 200-750℃); high temperature type (above 750℃). Principle The working principle of the fuel lithium battery is relatively simple. It mainly includes the two electrode reactions of fuel oxidation and oxygen reduction and the ion transmission process. The early fuel lithium battery structure was relatively simple, as long as the electrolyte transported ions and two solid electrodes. When hydrogen is used as fuel and oxygen is used as oxidant, the cathode and anode reaction and total reaction of fuel lithium battery are respectively: anode: H2→2H＋＋2e-cathode: 1/2O2＋2H＋＋2e-→H2O total reaction: H2＋1/2O2→H2O among them, H2 passes through Diffusion reaches the anode and is oxidized to e- under the use of a catalyst. After that, H+ reaches the cathode through the electrolyte, and the electrons also reach the cathode through the external circuit to drive the load to perform work, thereby undergoing a reduction reaction (ORR) with O2.
