Portable, ultra-advanced fuel-cell power generators based on the H 2 O-GEN TM technology

H 2 O-GEN TM technology Portable fuel cells (PFCs) cover a little fraction of the world market, which is hardly explainable if one considers the huge number of commercial applications in the 50-250 W power range (Table 1).

H 2 O-GEN TM technology There is little doubt that a major issue hampering the commercial diffusion of PFCs in the power range from 100 to 250 W is the hydrogen source. Systems that make use of compressed hydrogen are not attractive for the need of carrying heavy and unsafe cylinders with limited autonomy (generally 1 or 2 normal cubic metres of hydrogen) and difficult recharging procedures.

H 2 O-GEN TM technology WORGAS BRUCIATORI Srl has developed fully autonomous and portable "off-grid" power generators with an effective power output of 100 W, based on advanced on-board hydrogen generators and PEM fuel cell stacks. Essential components of the power generators are proprietary and advanced catalytic reactors for either sodium borohydride (reaction 1) or metal composite (reaction 2) hydrolysis, known with the trade mark H 2 O-GEN. As shown in reaction (1), half of the hydrogen produced is extracted from water which is therefore a reagent and an effective hydrogen-storage material. Likewise, all the hydrogen produced upon alkaline hydrolysis of a proprietary metal composite is essentially released by water (reaction 2). cat NaBH 4 + (2 + x) H 2 O 4 H 2 + NaBO 2. xh 2 O (x = 2 4) (1) M + x H 2 O M(OH) x + x/2 H 2 (2)

H2O-GENTM technology The H2O-GEN technology involving NaBH4 hydrolysis shows its maximum degree of innovation in the way the hydrolysis catalyst is immobilized and activated as well as in the control system of the hydrolysis temperature and the composition of the borohydride co-reagent. WO2013/021242 A1; WO 2013/021243 A1)

H 2 O-GEN TM technology With NaBH 4 as water activator, hydrogen fluxes as high as 2 L/min can be steadily obtained. Sodium borohydride is provided in the form of a composite material sealed in plastic cans with appropriate volumes to produce the desired amount of energy (a standard cartridge provides 750 Wh). Estimated cost of 1 kwh to the end user: 25-35

H 2 O-GEN TM technology The reactor involving metal composite hydrolysis (reaction 2) is based on a proprietary, intellectually protected technology allowing for an effective control of the hydrogen flux which can be as high as 12 L/min, hence potentially able to feed up to 1 kw PEM stacks. This type of H 2 O-GEN TM power generator is provided with four cartridges for an overall energy of 1 kwh. Most importantly, the H 2 O-GEN TM reactor with the metal composite activator can be used innumerable times as the recyclable cartridge is the reactor itself. Estimated cost of 1 kwh to the end user: 5 (lower gravimetric hydrogen capacity as compared to NaBH 4 activator) PCT/IT2013/000022; PCT/IT2012/000397)

H 2 O-GEN TM technology For portable applications, the hydrogen generators can effectively operate at external temperatures ranging from -15 C to 40 C. When used to feed a 140 W (peak power) PEMFC stack, the hydrogen flux is fixed around 1.8 L min -1 at 0.3-0.4 bar, but the modularity of the hydrolysis reactors and of the fuel cell stacks allows for different customizations. In particular, the power range can easily be expanded for flexible adaptation to the requirements of the application. The devices are practically silent and neither carbon monoxide nor carbon dioxide is emitted, which allows the power generators to run indoors with no problem. The hydrolysis exhausts (alkaline solutions of inorganic salts) can be disposed by regulated procedures.
