The pyroelectricity phenomenon – crystals converting thermal energy into power – has been known since antiquity. Our ancestors observed that tourmaline thrown into a fire attracted and then repelled ashes. Seventeenth-century scientists began studying the effect in detail, discovering the electric charges are the result of modified crystal structures.
A fuel cell stack is a living organism and individual cell voltages report its vital signs. Which is why fuel cell vehicles are usually equipped with a monitoring system promptly drawing attention to critical operating conditions and enabling immediate response. It is absolutely necessary to reduce system costs before mass production can begin. Automated installations is a good place to start.
New times call for new ideas – and new materials. A global increase in electrification calls for new chemical products. Petroleum catalysts are a major component of the fossil fuel era and must be replaced. The current battle for rare natural resources and chemicals makes it all the more important to invest in research on inexpensive, readily available alternatives. Evidence points to nickel, tin and copper, and their undiscovered properties, as cheaper options. Good news for the electrolyzer and fuel cell industries.
Bipolar plates, or BPPs, are one of the most common components in fuel cell stacks. So, which BPP is put in a stack has a huge impact on functionality and costs. Three research projects, InProPlate, PreCoil and BePPel, funded by the German hydrogen and fuel cell program NIP II, have come up with new techniques that, above all, promise a significant reduction in manufacturing and measurement costs.
Leaders are in the hot seat. The German government is expected to fix it all – the Covid-19 crisis, the climate crisis, the energy crisis, and the auto industry crisis. Summit after summit after summit. We’re hearing an awful lot from the chancellor, ministers, business leaders and lobbyists these days. And comparably little from parliament, where the laws are actually passed. But which political topics or summits are truly relevant to hydrogen and fuel cell technology?
Amendments cut clean energy surcharges on hydrogen
Experts agree, German parliament has scored an important hydrogen economy victory. EEG,amendments exempt hydrogen from a good portion of clean energy surcharges. What we need now is a renewable capacity to match.
