PEM vs SOFC Fuel Cell Simulator

Hydrogen fuel cells convert chemical energy straight into electricity by moving an ion across an electrolyte between two electrodes — but which ion, and at what temperature, depends entirely on the chemistry. This simulator puts a low-temperature PEM polymer-membrane stack and a high-temperature solid-oxide ceramic stack side by side on one shared temperature axis, so you can watch proton conductivity in the PEM membrane collapse as it dries out while the SOFC's oxygen-ion conductivity only wakes up hundreds of degrees higher. Sweep temperature and load to see how each chemistry's polarization curve — and therefore its practical use in mobile versus stationary hydrogen applications — falls out directly from that one physical difference.
