Abstract

Due to the current energy crisis, new forms of alternative energy are needed. The fossil fuels used today are a finite fuel source and produce large amounts of CO2 gas which contributes to climate change. There are alternative energy sources such as solar power which provide a clean renewable form of energy, however, they are intermittent meaning they only work under certain conditions. The energy from these intermittent sources can be used to electrochemically reduce CO2 into formate. Since formate can be used as a fuel source, reducing CO2 into formate can store the energy released from the intermittent sources for later use. Formate has been shown to be competitive with ethanol and methanol making it an attractive fuel source. The device created houses a direct formate fuel cell (DFFC) and a section where the reduction of carbonate occurs. The DFFC side of the device uses the oxidation of formate to produce carbonate which releases energy. The other end reduces carbonate by using a Sn catalyst to produce formate. Combining these two sections, the device could be used to store energy through the reduction of carbonate to formate and use this formate as the fuel allowing it to store energy from intermittent fuel sources. The device was able to produce a power density of 2mWcm-2 using the formate made from the device. To produce formate, commercial Sn and Sn on carbon (SnC) were used and compared. The commercial Sn was premade commercially while SnC was synthesized and was measured with XRD to confirm the presence of Sn. To quantify the amount of formate produced, HPLC and NMR were used. The highest concentration of formate produced was at -1.875V for both catalysts. This device could be used in the future to provide a clean energy storage unit for reusable energy sources.
