TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The membrane electrode assembly further comprises solid polymer electrolyte membrane (11) or at least one gas diffusion backing (13).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The cyclic tert. amine comprises at least one saturated monocyclic, bicyclic or polycyclic ring containing at least one tert N atom, where the number of ring atoms is 3-18. It comprises at least one carbon, nitrogen, oxygen or silicon. It comprises at least two saturated cyclic amine rings, where the rings are linked to one another by a linking group selected from linear alkylidene, cyclic alkylidene, oxyalkylidene, polyoxyalkylidene, alkoxylated alkylidene, or alkylaryl groups 1-100C atoms. It consists of compounds of formulae (1)-(3). It comprises at least two saturated cyclic amine rings, where the rings are attached to polymeric cores by side chains. It is an end group of dendrimer. The dendrimer is a dendrimer polyether. It is based on successive generations of polypropylenimines substituted onto a central diamine. The central diamine is ethylenediamine, in which the terminal amine end groups are part of saturated cyclic rings.n=2-100 (formula 1), 1-100 (formula 2) or 1-50000, preferably 1000-10000 or 1-20 (formula 3).Preferred Properties: The cyclic tert. amine has a molecular weight of 200-1000000 (preferably 400-2000).Preferred Compositions: The methanol fuel comprises at least 0.001 (preferably at least 0.1-2.0) M performance additive.    TECHNOLOGY FOCUS - POLYMERS - Preferred Compounds: The polymer binder is a highly fluorinated ion-exchange polymer, optionally containing sulfonate ion exchange groups.Preferred Compositions: The polymer binder is present at greater than or equal to5 (preferably 10 to less than 20) wt.%. EXAMPLE - Methanol fuel (27 g) was loaded in fuel compartment. The cell potential was set at 0.45V constant and the current output was monitored as a function of time. At the 30 minutes mark, 4,4'-(Oxydi-2,1-ethanediyl)bismorpholine (1.15 cm3) was injected into the fuel compartment to result in 0.175 molar of the additive. The cell current increased from 134 mA to 142 mA. Methanol crossover in the cell with the additive was 7 mA/cm2, while methanol crossover in the cell without the additive was 110 mA/cm2.
