Non-membrane diffusion is elim<strong>in</strong>ated by avoid<strong>in</strong>g <strong>in</strong>erts <strong>in</strong> the system<br />
• Automation of dynamic system assures cont<strong>in</strong>uous diffusivity measurements at a variety of relative<br />
humidity;<br />
• Process simple, effective, <strong>and</strong> accurate, open to other researchers <strong>in</strong> fuel cell community<br />
