A design of experiments (DOEs) coupled with a mathematical model was used to quantify the factors affecting methanol crossover in a direct methanol fuel cell (DMFC). The design of experiments examined the effects of temperature, cathode stoichiometry

A new concept that enables fully passive CO2 gas bubble removal in micro direct methanol fuel cells (μDMFCs) is presented. The original concept behind the presented degassing structure (flowfield) is based on microchannels with a T-shaped cross sect

Air-breathing PEMFCs consist of an open cathodic side to allow an entirely passive supply of oxygen by diffusion. Furthermore, a large fraction of the produced water is removed by evaporation from the open cathode. Gas diffusion layers (GDLs) and the

The impact of structural parameters and operating conditions has not been researched yet for vapor-fed operation of a DMFC at near-ambient conditions. Thus, a detailed parameter study that included reference cell measurements to assess anode and cath

Reference cells are used to distinguish between polarization losses of the anode electrode and the cathode electrode in an electrochemical system. In the case of a direct methanol fuel cell (DMFC), a reference electrode can either be attached using a

A vapor-fed DMFC with completely passive operation on both anode and cathode sides was demonstrated and employed for the research of structural parameters and operation under ambient conditions. By applying reference electrodes which were screen-prin
