Er ist hier an ein Kohlenstoffatom und ein Sauerstoffatom gebunden, die chemische Formel von Methanol ist CH<sub>3<\/sub>OH. Das Methanol wird dann im Wagen auf rund 300 Grad Celsius erhitzt, ein Katalysator spaltet das Methanol dann in Wasserstoff, Kohlenstoff und Sauerstoff. Kohlenstoff und Sauerstoff scheiden wir als CO<sub>2<\/sub> in die Luft aus, der Wasserstoff erzeugt den f\u00fcr den Antrieb n\u00f6tigen Strom.  <\/em>   <\/p>\n\n\n\n<p><em><strong>SPIEGEL:<\/strong> Im Gegensatz zu einem reinen Wasserstoffauto st\u00f6\u00dft der Wagen dadurch aber CO<sub>2<\/sub> aus &#8211; ist so ein Auto wirklich umweltfreundlich?     <\/em><\/p>\n\n\n\n<p><em><strong>Gumpert: <\/strong>Wir verwenden ausschlie\u00dflich gr\u00fcnes Methanol, das zum Beispiel in der Holzindustrie mithilfe von gr\u00fcnem Strom gewonnen wird. Dabei wird Wasser in Wasserstoff und Sauerstoff zerlegt und dann mit Kohlendioxid, das zum Beispiel bei der Papierherstellung entsteht, zu Methanol umgewandelt. Dadurch ist der Treibstoff CO2-neutral. Wir garantieren, dass unsere deutschen Kunden gr\u00fcnes Methanol bekommen.<\/em>     <\/p>\n\n\n\n<p>\u2026..<\/p>\n\n\n\n<p><em><strong>SPIEGEL:<\/strong> Methanol verbrennt bei Sonnenlicht unsichtbar. Ist das nicht ein gro\u00dfes Sicherheitsrisiko?  <\/em>   <\/p>\n\n\n\n<p><em><strong>Gumpert: <\/strong>Methanol ist deutlich weniger gef\u00e4hrlich als Benzin. Es verbrennt mit einer blauen Flamme, die bei hellem Licht schwer sichtbar sein kann, ist aber deutlich schwerer entflammbar als Benzin. Auch die Explosionsgefahr ist deutlich geringer. Au\u00dferdem ist Methanol nicht gef\u00e4hrlich f\u00fcr die Umwelt, wenn es versch\u00fcttet wird, und es kann mit Wasser gel\u00f6scht werden.

The 10 l fuel cartridge costs approx. 45 \u20ac in the specialized trade.  <\/p>\n\n\n\n<p>We used a 10 l cartridge in 5 weeks Sassnitz &#8211; Stockholm &#8211; Sassnitz during our last vacation, mainly to cover some longer stretches without an overnight stay in port, some days in anchor bays and some weeks of charge state maintenance in a total of 6 weeks of layovers without shore power in Sweden. During this time, the fuel cell has run a total of between 160 h and 180 h, delivering an average of just over 5 amps of charging current. &nbsp; <\/p>\n\n\n\n<p><strong>positive: <\/strong><\/p>\n\n\n\n<p>quiet, absolutely easy to handle, works fully automatically in the background, comfortable remote control with level indicator for the cartridges. Change of cartridges very easy and safe to handle. Setting option for adaptation to individual operating requirements via remote control, e.g. threshold values for switching on and off.&nbsp;<\/p>\n\n\n\n<p><strong>negative:<\/strong><\/p>\n\n\n\n<p>expensive both to purchase and to consume. The device requires the cartridge to be changed before it is really empty. There remains a residue of just under 10% in the cartridge, which also cannot be decanted to refill another cartridge. As far as I know, there is also no return system for the emptied cartridges.<\/p>\n\n\n\n<p><strong>Correction on 14.10.2020: <\/strong>The cartridges are actually completely emptied. Only if you sail with heeling while the fill level is running low, there remains a natural rest \ud83d\ude09 \u2026 If the ship then later is not heeling anymore, you can restart the device and the canister is then completely emptied. Sorry, was my mistake. <\/p>\n\n\n\n<p><strong>Conclusion: <\/strong><\/p>\n\n\n\n<p>The aim is to be able to spend several days at anchor when cruising without having to constantly check the charge level of the consumer battery. The solution should be comfortable and unobtrusive and also be able to withstand rough sailing. I did not want to have complex technology on deck for the extraction of wind or solar energy or a heavy generator. Measured against these requirements, I am very satisfied and can only recommend the solution for similar requirements. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>We have been using an Efoy Comfort 140 fuel cell to supplement the charging power on our 39 foot sailing yacht since early 2019.
