    Fabrication and properties of polymer electrolyte membranes (PEM) for direct methanol fuel cell application
    (Elsevier, 2021) Aydın Ünal, Fatma; Erduran, Vildan; Timuralp, C.; Sen, Fatih Gürça?
    Because of its simple handling and low temperature sensitivity, the direct methanol fuel cell (DMFC) system is very important to the development of energy converters. Also, the factors that inhibit the commercialization of DMFCs have a number of negative effects, such as the sensitivity of the polymer to the osmotic swelling of the electrolyte membrane, the passing of methanol through the membrane, the high cost, and the limited working temperature. The prepared product is based on the production and properties of polymer electrolyte membranes (PEMs) used in DMFC applications. © 2021 Elsevier Inc. All rights reserved.

    Porous metal materials for polymer electrolyte membrane fuel cells
    (Elsevier, 2021) Aydın Ünal, Fatma; Timuralp, C.; Erdurancd, Vildan; Sen, Fatih Gürça?
    In the structure of the polymer electrolyte membrane fuel cell (PEMFC), there is a need for porous electrodes in order for the gas to move to the active regions of the electrocatalysts. The electrode should provide a loud surface catalyst field to maximize the reaction ratio (current density) and minimize electrode polarization. In this chapter, the PEM provides information on porous metal materials for fuel cells. © 2021 Elsevier Inc. All rights reserved.
