(#113) Fixing Industrial Fuel Cell Thermal Failures

Mechanical Engineering Made Simple · Mar 13, 2026 · 52m · transcript

This episode throws you into the role of a lead engineering troubleshooter called in to save a failing 1 MW hydrogen oxygen fuel cell power plant before a full hard shutdown. What starts as a collapsing electrical output quickly turns into a chain reaction of thermal overload, microscopic contact resistance, pump deadheading, laminar flow bottlenecks, fouled heat exchangers, and broken shell-side flow geometry. Step by step, we break down how chemical thermodynamics, Gibbs free energy, thermal boundary resistance, dimensional analysis, Reynolds number, twisted tape inserts, LMTD, fouling…
