The enhancement of proton transport in polymer electrolyte membranes (PEM) is an important issue for the development of fuel cell technology. The objective is a material providing proton transport at a temperature range of 350 K to 450 K independent from a purely water based mechanism. To enhance the PEM properties of standard polymer materials, a class of additives is studied consisting of functionalised mesoporous silicon dioxide particles. The main interest of the computer based research lies on the description of the proton conducting abilities of the novel material. Besides hydrogen bond...
