Marathon more than 10,000 kms from Hammerfest to Lisbon with one Opel Zafira fuel cells car. On the 2nd of June Salzburg is in the row. Opportunity for a test run.

On the 10,000 kms of marathon through Europe this cut car Opel Zafira is to be seen in the accompanying truck for press conferences also.

| Hydrogen compression tank for fuel cell cars
|
| 
|
|
|
Only 3.4 kgs of hydrogen instead of 4.6 kgs in liquid hydrogen tank. For it, however, no losses by vaporization. For opportunity drivers on short distances the better solution.

| Liquid hydrogen tank for a hydrogen car
|
| 
|
|
|
Here built into an Opel Zafira. However, with 4.6 kgs about 400 kms of reach, for it hydrogen gets lost constantly by warming in the tank and the vaporization resulting from it.

| Test drive Opel Zafira hydrogen fuel cell car
|
| 
|
|
|
Only gas pedal and brake. No gearshift but only push buttons for Forward, Backward and parkings. Thus it is a matter of disusing the left foot for the test run for the first time.
|
| Fuel cell in Opel Zafira
|
| 
|
|
|
200 fuel cells in series produce 125 to 200 volts. Top power 94 kW. The power density is 1.6 kW per liter or 0.94 kW per kg.

Where otherwise the engine is, is the fuel cell and about that point the voltage converter. It converts the delivered electric power to a higher voltage for the electric motor .
|
| Tank conection for hydrogen
|
| 
|
|
|
Tank fill conection for liquid hydrogen. Not to warm up the extremely cold liquid hydrogen on the way to the tank and to gasify therefore a lot of technology is necessary.

| Railway station Salzburg: stage of the hydrogen Zafira
|
| 
|
|
|
On the 2nd of June, 2004 the fuel cells Opel Zafira marathon stops in Salzburg. About 60% of 10,000 kms of tour of Hammerfest to Lisbon have already gone.
|
| Start from Salzburg toward Turin
|
| 
|
|
|
The next stage to Turin goes more than about 730 kms. While today's diesel cars of this size have loosely 1300 kms of reach, here it goes only with tank stop.
|
| Test car fuel cells Opel Zafira
|
| 
|
|
|
With the 10000 kms marathon are 2 fuel cell cars. While the real marathon car is underway towards Turin, the second is available for test runs.
|
| Opel Zafira consumption
|
| 
|
|
|
1.2 kgs of hydrogen on 100 kms in the European consumption cycle. However, hydrogen is very full energy with 33.3 kWh per kg. There are about 40 kWh on 100 kms.
|
| Hydrogen car: really the future?
|
|
|
Can this really be the future? Especially both tank solutions are not satisfyingly. With normal temperatures liquid fuel has many advantages.
