IC HydroC: comparison

Platinum-free hydrogen power, built for harsh environments

The lightest air-cooled PEM stack we know of, and the only one proven at −40 °C

Key stats:

Why platinum-free matters

Oxygen reduction at the cathode is the slowest step in a fuel cell, so it needs a catalyst. Platinum works but is costly. Iron–nitrogen–carbon (Fe‑N‑C) catalysts avoid platinum; the concave design brings active sites to the surface where oxygen can reach them.
