A Novel Approach on Proton Exchange Membrane Free Direct Formic Acid Self-Electrolyte Fuel Cell

Abstract:

A novel approach was performed to eliminate the expensive proton exchange membrane (PEM) from the direct formic acid fuel cell (DFAFC). In the new designed PEM-free direct formic acid self-electrolyte fuel cell (SEFC), formic acid performed the functions of both fuel and ion conductor because of it can be ionized in the aqueous solution. Porous PTFE film was used as the separator in the SEFC to isolate the electron transport inside the fuel cell. This acidic SEFC utilizing Pt as anodic/cathodic catalysts can achieve a power density greater than 1.0 mW cm^–2, which was about 1/5 of that of a traditionally PEM-equipped DFAFC with the same catalysts, after the optimization of thickness and porosity of the porous PTFE film.
