A fuel cell is a device that generates electricity by a chemical reaction
The operating principle of the fuel cells is based on the oxidation of a fuel (e.g. hydrogen) and the reduction of a comburant (e.g. oxygen) leading to the simultaneous production of water, electrical energy (W) and heat (Q). This consists of two electrodes one emitting electron( anode) and the other receiving electrons (cathode), separated by an electrolyte allowing the passage of ions. A membrane prevents the contact of the anode and cathode reagents.
oxidation of the oxygen on the Anode: H2 → 2H+ + 2e-
reduction of the oxygen on Cathode: 1⁄2O2 + 2H+ +2e- → H2O
Global reaction: H2 + 1/2 O2 → H2O
Each type of fuel cell is characterized by the electrolyte adopted. If we except the batteries “AFC” (with potash), four categories are currently envisaged for building applications, applications designated by their English acronym. It’s about :
. so-called PEMFC (or PEFC) batteries,
. so-called MCFC batteries,
. SOFC batteries,
. so-called PAFC batteries.
These different categories are characterized by the following electrolytes.

Cold Weather Starting
Insulating the fuel cell system and its balance of plant components properly can keep the system from freezing for 8–24 hours or longer. If no heat is delivered to the system by running, battery discharge, or fuel burning, the system will eventually freeze and will need to be restarted. 
In terms of environmental compatibility, consumer profit, maintenance costs, and efficiency, fuel cell technology has the potential to outperform today’s motive power techniques.
The only significant obstacle remaining that of the cost, it is possible to hope that current research will help mitigate, if not to eliminate this defect, but the forecasts are not conclusive, and there are still many uncertainties (see opposite forecasts for the period 2015-2020).
