A solid/liquid bridges the gap : Although the intermediate temperature range (150–500°C) is of increasing interest for fuel cell technology, suitable electrolytes were not available. A new strategy based on solids with liquidlike properties—highly proton‐conducting plastic phases of acidic, hydrogen bonded sulfates or phosphates—may close this temperature gap. In this Highlight, other alternative concepts are also explored.
