In proton exchange membrane fuel cells, perhaps the most divulgate type of fuel cells, a proton-conducting polymer membrane acts as the electrolyte separating the anode and cathode sides. Porous anaodic alumina (Bocchetta et al., 2007) and mesoporous anastase ceramic membranes have been recently introduced in this field (Mioc et al., 1997 Colomer and Anderson, 2001 Colomer, 2006).

From the second half of twentieth century, acidic (proton exchange) Polymer Electrolyte Membrane Fuel Cells (PEMFC) have attracted much attention due to their potential as a clean power source for portable applications (alcohol feed). 

Polymer Electrolyte Membranes or Proton Exchange Membrane Fuel Cells (PEMFCs). PEMFGs use a proton conductive polymer membrane as an electrolyte. At the anode, the hydrogen separates into protons and electrons, and only the protons pass through the proton exchange membrane. The excess of electrons on the anode creates a voltage difference that can work across an exterior load. At the cathode, electrons and protons are consumed and water is formed. 

Esquivel et al. (2010) present an all-polymer micro-DMFC fabricated with a SU-8 photoresistor. This development exploits the capability of SU-8 components to bond to each other by a hot-pressing process and obtain a compact device. The device is formed by a MEA sandwiched between two current collectors. The MEA consists of a porous SU-8 membrane filled with a proton-exchange polymer and covered by a thin layer of carbon-based electrodes with a low catalyst loading (1.0 mg/cm ). The current collectors consist of two metalhzed SU-8 plates provided with a grid of through-holes that make it possible to deliver the reactants to the MEA by diffusion. The components were then bonded to obtain a compact micro-DMFC. With this assembly, using a 4 M methanol concentration at a temperature of 40°C, a maximum power density of 4.15 mW/cm was obtained.
