Abstract

Over the last thirty years the total U.S. energy consumption has doubled, and is expected to continue growing. This rate of growth is unsustainable and is causing irreparable damage to the environment. Although the vast majority of current energy comes from non-renewable sources the last decade has seen a very significant rise in power coming from renewable sources such as solar and wind. These renewable sources of energy are more environmentally friendly, but they are also intermittent and require additional devices in order to use power when they are unable to generate it. For this purpose, we created a device which can reduce carbonate to formate in order to store renewable energy as a fuel to be used in a Direct Formate Fuel Cell (DFFC). This device integrates these two components together to hold liquid fuel in a central reservoir for an overall carbon neutral process. After thirty minutes of carbonate reduction the concentration of formate in the device was determined to be 100 mM using an Ultraviolet-Visible Spectrophotometer. The overall faradaic efficiency of our integrated device was found to be 39.74 % and produce 2 mW/cm2 of power density after only fifteen minutes of carbonate reduction.
