In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The importance of water transport in high conductivity and high-power alkaline fuel cells, published in 2020, which mentions a compound: 111-18-2, mainly applied to water transport norbornene polymer alk fuel cell, Category: thiazole.
High ionic conductivity membranes can be used to minimize ohmic losses in electrochem. devices such as fuel cells, flow batteries, and electrolyzers. Very high hydroxide conductivity was achieved through the synthesis of a norbornene-based tetrablock copolymer with an ion-exchange capacity of 3.88 meq/g. The membranes were cast with a thin polymer reinforcement layer and lightly cross-linked with N,N,N’,N’-tetramethyl-1,6-hexanediamine. The norbornene polymer had a hydroxide conductivity of 212 mS/cm at 80°. Light crosslinking helped to control the H2O uptake and provide mech. stability while balancing the bound (i.e. waters of hydration) vs. free H2O in the films. The films showed excellent chem. stability with <1.5% conductivity loss after soaking in 1 M NaOH for 1000 h at 80°. The aged films were analyzed by FTIR before and after aging to confirm their chem. stability. A H2/O2 alk. polymer electrolyte fuel cell was fabricated and was able to achieve a peak power d. of 3.5 W/cm2 with a maximum c.d. of 9.7 A/cm2 at 0.15 V at 80°. The exceptionally high current and power densities were achieved by balancing and optimizing H2O removal and transport from the H neg. electrode to the O pos. electrode. High H2O transport and thinness are critical aspects of the membrane in extending the power and c.d. of the cells to new record values.
