Dr. Khe Nguyen is developing two types of clean power generators: 1) A power generator from water that uses electrolysis to produce hydrogen from water, which is then converted to electricity through a PEM fuel cell. 2) A power generator from pure hydrogen gas that stores purified hydrogen gas in a compressed tank, which then feeds the hydrogen directly into a PEM fuel cell and inverter to produce AC power. Both types of generators have advantages like being noiseless and emission-free. Dr. Nguyen is working to reduce manufacturing costs and has demonstrated a 2000W power generator from water. He is seeking partners to help with product design, manufacturing, and commercialization.

2. WE ARE DEVELOPING TWO DIFFERENT KINDS OF CLEAN POWER GENERATOR
a) POWER GENERATOR FROM WATER :
• WATER IS THE RESOURCE PRODUCING HYDROGEN WHICH CAN BE CONVERTED INTO
ELECTRICITY TROUGH A PEM FUEL CELL
• DIRECT CURRENT FROM THE PEM FC GOES THROUGH A REGULATOR TO PROVIDE EQUAL
VOLTAGE
• THE REGULATED CURRENT IS STORED IN A CAPACITOR
• THE STORED DC FROM THE CAPACITOR IS CONVERTED INTO AC USING AN INVERTER
• CUSTOMER CAN INSERT THEIR PLUG AND USE IT RIGHT AWAY , ESPECIALLY IN THE
EMERGENCY CASE OR IN OUTDOOR ACTIVITY
a) POWER GENERATOR FROM PURE HYDROGEN GAS
• THE HYDROGEN GAS GENERATED FROM WATER IS PURIFIED WITH WATER AND STORED
IN A COMPRESSED & COMPACT HYDROGEN GAS TANK
• THE PURE HYDROGEN GAS TANK IS CONNECTED TO PEMFC AND INVERTER TO PRODUCE
AC
• THERE IS NO NEEDS FOR REGULATOR, CAPACITOR
a) ADVANTAGES OF CLEAN POWER GENERATOR
• NO NOISE
• NOCARBON EMISSION
• WE are working on FUEL CELL COMPONENTS SUCH AS GAS DIFFUSION LAYER (GDL), PEM,
MEA, BIPOLAR PLATE, CATALYST TO REDUCE MANUFACTURING COST .
• WE HAVE DEMONSTRATED 2000W POWER GENERATOR FROM WATER IN JANUARY 2012
• WE ARE LOOKING FOR PARTNER WHO CAN HELP OUT PRODUCT DESIGN,
MANUFACTURING AND COMMERCIALLIZATION

2. OPERATING AT ROOM TEMPERATURE H2O
3. NO NEED TO USE ANY POWER SOURCES FROM

4. COMPACT SIZE
5. NO NOISE
6. NO POLLUTED AIR
7. POWER GENERATOR AND WATER PURIFIER
WILL BE BORN TOGETHER

15. PROBLEM OF DIRECT POWER GENERATOR FROM WATER
1. SHORT DURATION OF H2 GENERATION (MAX 30MIN)
2. MULTIPLICATION OF SEPARATED H2 GENERATORS INCREASES
THE BUKINESS OF THE SYSTEM
3. WE MUST FIND ANOTHER H2 GENERATOR WHICH CAN STABLY
PROVIDE H2 CONTINUOUSLY 3 Hours
4. ANOTHER SOLUTION : DEATACH H2 GENERATOR SYSTEM FROM
POWER GENERATOR AND CONVERT IT INTO CLEAN POWER
GENERATOR WHICH IS COMPRISED OF H2 CONTAINER, PEM FC
STACK, CONVERTER (WATER CONTAINER, REGULATOR,
CAPACITOR ARE ELIMINATED)
5. WE DO NEED HELPS IN THE INDUSTRIAL DESIGN OF THE SYSTEM,
THE COVER, etc…
