A polymer electrolyte membrane for a fuel cell includes a polymer matrix comprising a cross-linked curable oligomer with nano-sized proton conductive polymer particles in the polymer matrix. The device includes a RF signal receiving module, a bridge module and a USB module, which can operate in normal mode, first idle mode, second idle mode or search mode. , 1 to 10 parts by weight of high viscosity mineral oils andor synthetic oils having dynamic viscosity of 100 mm2s or higher at 40\xb0 C. DC thermal energy generators are instantiated on the PLD adjacent the critical paths to heat the critical paths to one or more test temperatures. The core may contain nitrogen and the coating material may include one or more linear, saturated aliphatic monocarboxylic acids. The first leg engages the first indentation of the first side of the contact stab and the second leg engages the second indentation of the second side of the contact stab, thereby retaining the clip member on the contact stab.
